Awesome- learned more from you in 12 mins than 50 years spent listening to to dribble from so called professionals
Thank you so much brotha! You really have a talent for this stuff, super clear and concise, understood everything you said, and, it was actually really fucking good info. I have a VT 3.8L L67 supercharged 98 calais and this fixed the idle 100%. After spending 100 dollars on new leads and $150 on spark plugs, you solved my problem with $2 worth of petrol and a toothbrush lol...Legend.
+Kittencoup no worries mate :) glad you found my vid helpful :). I can't afford to pay a mechanic so I understand how important info like can be
Kittencoup
Do you still have the VT L67 Calais?
thanks, and your absolutely correct. that's why it's important to not use brake fluid from a container that's been opened then stored for a period of time. and to change brake/clutch fluid regularly because it absorbs water and lowers the boiling point of the fluid(which when new should be around 200 deg C) which causes brake fade when the brakes get hot. which is a pain if you want to stop.
great video,probs one of the best explained car videos if have watched.welldone
I've definitely subscribed , great videos with excellent details, a tonne of info 😊
Thank you very much mate :) Anything you would like me to make a video about please let me know :) petersmyth79@yahoo.com
wickedxe hey I have a question
I have a vt 99 ,6 cylinder
I've changed,
Feul filter
Feul pump relay
Maf sensor
Cleaned throttle body
Idle speed valve
Spark plugs
Sometimes when starting the car it will run rough for about 10 secs then smooth out , was stalling sometimes at idle before changing those things
What do you think it could be ?
Coolent sensor ?
Any help would be appreciated
This was very helpful on fixing the idling issue I had on my VU Ecotec. After cleaning the throttlebody, and upgrading some hose clamps, it purrs like a kitten.
Very good video. Glad it popped up when searching. I was about to look for an adjustment screw! Oops! ;) My 2004 VY Commodore Wagon has had a rough low idle problem since I got it 2 years ago. When turning the steering wheel or shifting and reversing it stumbles badly then recovers. The car originally had LPG fitted too. When they removed it they blocked the extra drilled injector manifold holes with bolts. So I guess also a potential source of a vacuum leak .-.-.
Well I pulled my finger out tonight and cleaned the butterfly and idle sensor. The sensor had a bit of carbon but it wasn't too bad. The idle improved but I still get it stumbling when I turn the power steering hard while stopped. Any further ideas? .-.-.
Thanks that was a good description of where the trouble may be and how to deal with it. I even enjoyed the extra info. Would you recommend disconnecting the PCV hose before cleaning the throttle body? Could you please make a video on how to change a fuel filter on your VT?
Hygroscopic is the word you're after - Brake and clutch fluid are the same.
This is why all containers have good seals to keep the fluid in the best condition - If the seal/cap for Brake or Clutch fluid is cracked/damaged/perished you should replace it.
incredibly helpful and informative - thank you
+danb3e3 Thank you very much for your kind words :)
Still helping people in 2021 brother, cheers.
Yes pls do more vids pls much appreciated. I have a vy commodore with an ecotech and I'd like to know more bout the engine so I know what to look for if something happens with it I know Eco's are way better then the alloys they have timing chain problems most of them
My vy v6 goes good, idles good in drive but idles ruff in park, any ideas please
Awesome video bro found it very simple an very effective info 👍👍
Thank you, glad you found it useful
Brilliant vid!!! thank you!!
Hey matey just like to know do you have a video on the air intake or bad idling for a vy commodore around years 03/04 duel fuel or just fuel and also fuel getting into the oil stick can’t find any at the moment on CZcams regarding that thanks keep up the good work mate
Thanks for the tutorial! My vx isles a bit low and fluctuating in diagnostic mode? Sprayed water around electrical wires( no arcs) spray water for vacuum leaks nothing? New Delphi ignition module and coil packs, 3 new coil packs, leads ,plugs. Cleaned inside of plenum. New TB gasket. TB clean.i didn't clean Tps or IAC? Any reply appreciated cheers from Australia just subbed.nice job.
thank you very much :) . i'm really glad you like it :)
Got a vs commodore on LPG gas not sure but could have gas leak do I need to take it to gas shop or could it be a hose
this blokes a classic, champion vid
hay bro I have a gas smell coming from my 2001 holden vx at back of the engine or leaking down to the gearbox but don't know from and I don't know were or what it coming from just wondering if you know or had that before . thanks
Have you done a video of the idle air control valve. I have a surging idle and suspect this to be the problem.

G,day m8,i have a problem with high idle but ,haven't found any vacuum leaks or other,seals in the intake (manifold are new) had this problem for a while,has LPG and i think the leak is after the airbox. any ideas
I FOUND THIS VIDEO JUST NOW, I HAVE BOUGHT A 2001 VU UTE AND ITS IDLING ROUGH, I WAS GOING TO CHANGE THE PLUGS AND LEADS BUT I WILL TRY THIS FIRST, THE CAR IS DUEL FUEL, CHEERS MATE
I've got a VX commodore (anniversary model), and have just cleaned throttle body and idle air control valve (the valve on throttle body that he showed).
We have also just cleaned air mass flow sensor (hint, can't just use any thing to clean it, need proper air mass flow sensor cleaner).
Like he said in video, we ourselves have never touched idle screw that he advised not to touch), however, a mechanic that I took my car to not that long ago has played with the cable and screw. He had the cable to tight and has threaded the screw itself...hence why we never touched it
Due to issues of car stalling, extremely rough idle, lack of acceleration sometimes or a sudden urge of power, sometimes hard start or not starting at all and at times there was a strong smell of fuel.
Not the mechanic who played around with the cable and screw, I got mechanic who normally go through who did a diagnostic, which came up with codes (cam sensor, EGR valve and showed the rpms are way to low.
Replace cam sensor and EGR valve.
A lot of people are unaware that EGR should be cleaned every so often (admittedly, I was one of them), so maybe a video explaining and showing that
Yeah I cleaned my old man's VS Wagon - I didn't know about that other sensor - I usually do the throttlebody every year anyway. Idles a fair bit lower now!
I have a 2008 VE Commodore and it keeps stalling when I'm going to stop and the idle comes down what could my issue be and how do I fix it
spot on . good vid
well put together mate....easy , simple just what mechanics dont want to see....lol
I think the doovalackey you called the MAP sensor is the purge control solenoid.
LOL yeah I realised after I shot the vid. I had a dickhead moment. You are absolutely right. I could not see the valve with my eyes due to it's location and assumed it was a map sensor, but I worked that out when I watched this video and could actually see it.
Cool bud it was much appreciated good vd
Another good video mate👍👍
Can you show one on changing the fuel regulator on the same motor
Actually a good video, thankyou sir
Hey, thanks mate, I do these videos for free and I will admit my old content is pretty poorly done but I really hope some of you did indeed save some $ and make your car idle more consistently
Very interesting video, learnt a lot from it , thank you
Great video mate thnxs
No worries
Thanks mate . Great explanation. I develooed a fault code P1372 on my 2003 vy commodore. I am suspecting Coil or Dfi for not firing or crank sensor. The car cranks but does not fire. Any tips?
If you're free I am happy to help on 0490231352
@@wickedxe Thanks Mate appreciated. Just found troubleshooting steps on the DFI and coils . Crankshaft sensor ok.
having trouble with vt rough idle has new plugs have measured ht lead resints have cleaned idle speed sensor
Hi, this is so helpfull. May you take a little more care for a stativ and illumination/Light. Cheers from Germany.
Top Job Bloke
if the ecu senses a vacuum leak, the ecu compensates for the extra air by injecting more fuel; hence the reason why it idles higher than normal
cheers mate
Hey bro if you do all this what els can you do bro?
Just wondering my car doesn’t have any gutts anymore I put my foot down and it’s still slow I changed all the leads spark plugs coil packs and still nothing
Could be a number of things, Fuel pressure low due to: clogged fuel filter or a buggered fuel pump, A buggered Mass air flow meter. I would check the fuel pressure. A rubber ballet hit against the underside of the tank can show you if the pump is a problem although an inline pressure gauge (like the kit on ebay) is a 100% accurate way of diagnosing fuel system issues. Did it happen suddenly or slowly over time?
Good video, thanks for taking the time to make it.
I was wrong when I pointed at the thing that I called a MAP sensor as that is actually the EVAP purge valve
Miss my old vs. was that exact colour too
awesome thanks
Hi there friend , I brought 2000 proton Wira auto ,.when I.switch on aircon rpm goes so down
You sir have a car
Good for you mate, can you kindly explain why you felt the need to share this useless information with the OP and everyone else reading the comments on his informative video? Intriguing.
Great Vid man, I think the word you were after was hydroscopic ? absorbs water from the air.
Thanks mate :) . Yep you are totally correct, that is exactly the word I was after
will go give it a clean now
That reminds me, I need to do this to my wife's ED falcon. it's a bit low and rough when the aircon kicks in
will go give it a clean now exact car same paint everything haha
need assistance in removal of injectors from ecotech v6
I will make a video asap
+wickedxe
thanks mate
Know of anyone who has done a video of a VT dash removal, to access the aircon parts behind said dash.

Carby Cleaner works Wonders on Throttle bodies!
you can get a fluid tester that tells you what the boiling point is, but i think it's quicker and better to just simply change the fluid in the system, which i am going to do a vid on too :) i want to pass on the knowledge i learned working as a mechanic for a number of years
VS crank angle sensor, balancer removal etc
vs ecotec had a MAF sensor not a MAP sensor.
I took my throttle body off and cleaned it and it was really dirty i also took that sensor off and cleaned inside there too put everything back together car started and idling perfect but now car feels sluggish and revs feel rough can't tell if it's because of mucking around with throttle body or car not liking the new oil i put in because i also did an oil change
Could be a vacuum leak? has it improved sence you have driven it a bit. Or did you tighten the hose clamps between the mass air flow meter and the throttle body duct? I have seen that as a problem and lol I did the exact same thing on my calais the other day, 1st time I have forgotten to do up that clamp
@@wickedxe Hasn't improved since driving and yeah put everything back together perfect not sure what causes this it's actually had this problem for years now but since cleaning throttle body it seems worse I mean car still gets up to 100km no trouble but sometimes it'll speed up like a rocket other times feels like i'm towing a caravan and I always run bp ultimate
@@grassyfieldz4578 Interesting problem. I will go and think about it more. ecotec v6? not a buick vr v6?
@@wickedxe Yeah ecotec v6 I just bought an aldl cable so going to see if it has any fault codes
@@grassyfieldz4578 they can be handy although I have yet to play with my software enough to get useful info out of it. It's also worth getting a copy of the factory manual (I could only get the factory book to install on a windows xp laptop)
sure dose :)
Thankyou
Yes please, do what makes you happy. But you know your VS etc, and are a great teacher. I love my VS wagon, but the “man” wants us to crush them and get into debt with crap cars we can’t afford?
I did just have my tps replaced twice! Don't wanna pull the throttle body off cause of it!! STILL IDLING HIGH! FIXED THE FLAIRING THOUGH😷😷😷
Is your car an ecotec or is it a VR Buick?
@@wickedxe buick
@@fip1167 Could have a vacuum leak, in the Buick a decent vacuum leak can cause high idle
Think I know what it is the Iac vavle im taking it back in for a roady tomorrow anyway I can't find a leak anywhere besides maybe on the plastic of intake
@@fip1167 I couldn't say without seeing the car but I have seen even the brake booster leak vacuum. you will just have to give it a very careful inspection
I'm buying ( stealing a dodge Ram with the viper spec motor! Lift kit, huge tyres. ( monster truck) I'm going to run over my vx commodore and my neighbours commodore. And any falcon/ commodore I see. My idle is high when cold. 950 to 1000 rpm after changing my tps? Piece of shit! Sorry mate. I'm frustrated! Lol. An oscilloscope video on commodore and falcon sensors would be great 👍. But with my budget I guess I'll be buying an E bike! 😆. Cheers mate 👍. I keep coming back to your videos.
The tps needs to be re-learned by the ecu, the high idle will calm down after a while; do a few wide open throttle take offs (like a freeway onramp) and that will take care of it. the scope isn't required as the sensor is basically a variable resistor (like a volume pot on an amp) and it is fed 5 volts by the ecu; the voltage varies depending on the TPS/ throttle position. The ecu is designed to self calibrate the tps sensor; you just need some WOT throttle take offs and it will be okay. Stick with the VX Commodore as anything from Chrysler is unreliable rubbish that you will want to burn in a very short amount of time of owning it
@@wickedxe thanks for the quick reply! Does that mean that I have to do the 40 minutes relearn procedure? That's why I mentioned RAM? Purely for ramming or running over the commodore. Lol. I was going to disconnect engine fuse or disconnect battery for about an hour and check all connections etc. Then reconnect battery? One day I'm going to but a techscan 2. Thanks heaps 🙂👍👍👍
@@wickedxe oh btw ! Yes Chrysler is shit. Especially the 300C. I've seem my brother rebiuld the heads on the 5.7 hemi. Valve seats sticking out of the heads?
so why did you stop talking i was learning ....lol xD

cactus???
Very tidy Ecotec / vs
'whether'...sorry, mum was a teacher. X
It's okay I'm not offended, I have aspergers syndrome so spelling is not natural for me
