stock setting for the TPS is supposed to be under 1 volt. the actual setting it was at before you messed with it is a perfect setting this info was direct from Ford
Thank you so much. After weeks of working on my 87 5.0 I couldn't figure out the rough idle after replacing just about everything from plugs to all new vac hoses. I was about to give up and found your video. It fixed it so far, I'm going to buy a new TPS today just to make sure, but ill enlarge the holes again if it does the same. Thanks again.
Got a 91 Merc GM that was running like crap, engine light on and off, etc. Followed your video method here and the car runs fine now. Had .888 volts to start. Check engine light flashes were 63-low voltage at TP sensor. I set it at 1.08 volts. I'll take it for a drive later, see how it goes. Thanks man for the video.
+Oldsmob455 Car started acting up again, checked the voltage at idle. Ran fine at .9 +- volts then voltage started fluxuating .9 to .1 all over the place. That's when the engine stalled. Got a new TPS a few days ago and it's been running fine. What a relief. Thanks again for the info.
Interesting tuning tip!! I was thinking you might want to index the sensor in case you need to remove it for some reason, that way you can put it right back into position without having to re-tune.
My 1990 Notch would not even fire with a bad TPS sensor....would start for a split second then shuts off. Installed new one and fired right up runs like a champ. Crazy it went bad in storage
My 92 Idles fine has no problem revving from 1000 rpm on up, but it almost feels like it has to fight to rev right as I press the gas pedal from a lower idle. Is that the symptom you were referring to when you said "all of the hesitation is gone"?
Thats the same exact TPS in my Buell XB12Ss, Harley Davidson wants $325 and they pretend they are running out. Motorcraft CX1133 is only like $35 bucks. Same with their 135 tooth 1 1/8" belt drives they put on all their 850lb baggers. They want $300, but its just a Continental CTAM Timing Belt HB135-118 Reference OE/OEM Number: HARLEY-DAVIDSON MC 4030700 G05001AKF, same kevlar belt. Never go to the stealerships for parts
I have a 93lx with a 306. I am having a frustraiting problem and will try to explain it as follows: I have sluggish acceleration off the line and the car sometimes stalls. Would a new tps sensor fix this irritating problem? Also, how hard is the install? and what would a dvom(digital volt ohm meter cost? Many thanks for your time
Oldsmob455, What voltage would you recommend for a 1995 SVT Cobra? At the moment I have a problem with the idle. My RPM needle bounces around way too much. And the engine even boggs out at times. (turns off while in use) Here is a list of a few mods done to my Cobra: V1 Vortex SC, shorty headers, Ford Lightning mass air intake, 39lb fuel injectors. The 302 engine is completely rebuilt for performance as well. Given the short summary of mods on my Cobra could you recommend a good reference for the TPS?
Hey! Thanks for posting this. I think I have a similar issue on my '91 LX 5.0, it doesn't pull very much at all from a dead standstill, but after about 3k rpm is when it starts to get up and move. It also revs relatively slow in neutral or park. I went to go diagnose this, however I can't get a volt reading from the TPS. I did what you did and pierced the green wire with a metal pin and then hooked the volt meter to it, but it just stays at 0. Any ideas of where else I could try piercing it, or where else to hook it up to?
Nope, got no CEL. I wouldn't be surprised if the entire TPS is junk but I imagine one of the previous owners did what you did; replaced the sensor but never adjusted it so it just felt slow. Ive been doing a decent amount of research on it and it seems like the consensus is get a reading from where the wire actually goes into the connector, but I need to take the module completely off for that and as far as I know the screws on the head of the TPS are stripped to god knows what so maybe that'll be a project for another day lol
Like stated, don't touch your TPS sensor. This isn't 1995 anymore, and the reverse engineering of the EEC has shown that as long as its above .49 and below 1.1, once started the EEC resets this value relative to zero. Below or above those values sends a fault code. Simple.
After replacing plugs, wires, coil, egr, all new vac hoses, I couldn't figure out the rough idle. Tried this and it actually fixed my problem for the first time in any youtube vid lol.
Mine I change the intake manifold to a slightly higher and now I have no throttle response not sure why. Maybe it's the throttle sensor or something else.
I have 1995 gt few bolt ons idle is very poor set timing n firing order but it didn't help ,will tps adjustment work or make a difference as same on fox body 5.0
Arturo, there are Mustang experts on youtube, unfortunately this gent is not one of them. I'm sure he's cool and all, but this is terrible advice he is spreading. Do a youtube search for Brew2L and follow his video on doing a base idle reset, then a TPS install and your car will be good as new.
I have a 94 5.o and I went threw everything replaced fuel pump filter and all new sensors when you go to take off she's fine but getting down the road it just don't wanna run any tips would help...
Ok, maybe I am wrong. I just know on my T TYPE i did the same thing after reading on the internet it was a good thing. It wasn't, i had to get a new TPS and after I set it within spec the car ran perfect. It ran fine before, no CEL, but it definitely ran better within spec. If it works for you great, i will shut up now
this does work and very well on these cars. I have done this mod on 2 different 5.0 cars and the difference is night and day. One was a stick car and the other an aod, does wonders for power, idle and throttle response. there is all kinda of lil tricks with these that cost nothing, I want another!
it looks like you live by me with your vid by the fair park. my car has not started in days. not sure why? could you help out? i'm the owner of swords & dreams on greenfield ave. my name is tom.
"oh it's spring loaded " 👀no shit Sherlock of course it's spring loaded how else is the computer gonna know the position of the throttle plate so it can disperse the right amount of fuel thus the problem lies somewhere else
I guess you know more than the team of engineers from ford. I guess through shit luck you got the position right. But its irresponsible to say this works, now someone else might do it and its DEFINITELY not the right way. Maybe I sounded like a dick when I said it, I didn't mean it that way, I just don't want people fucking their cars up.
You are not adjusting a carb on 69 camaro. Its computer controlled, which run great when all the sensors are adjusted within spec. You just cannot adjust sensors and go by feel. You have to find what the correct factory settings are, adjust it to that and leave it the fuck alone.
@@Oldsmob455 Ignore the uneducated, inexperienced trolls. I really appreciate the video. I own two OBD 1 Ford vehicles and it's amazing just how much just the slightest adjustment of the TPS affects the power and shifting of the vehicle! It feel likes getting your PCM tuned. Most these naysayers are probably thinking of more modern OBD 2 vehicles.
SEE BELOW... Quote " Jerrythenerdful 5 years ago This is complete rubbish. You can look at the Ford EEC strategy and see the computer doesn't care if the voltage is anywhere from just below .6 volts to 1.2 volts. The Ford firmware accepts any key-start voltage in that range as closed throttle.Doesn't matter what it is. 2.71 volts above that is considered WOT voltage, and anything between the key start and + 2.71 over that is part throttle. Ford intentionally did this so people in the field would not need to adjust the sensor. It's right in the code for the computer. That's why Ford doesn't have an adjustment.

This is absolute fact Jerrythenerful. I just referenced this video to help a friend diagnose his TPS voltage. Everything else in this video is garbage. As long as the TPS is ranging correctly through the voltage the base voltage should be between .6 and 1.2. I just fixed a car quoting this exact figure before I saw this video to help a friend who is long distance. I'm going to quote this to bring it back to the top!

Thanks for the easy to use guide. I replaced my IAC and never ran right afterwards.
Best TPS settings video on the internet.👍
Thanks. Man, this was a long time ago.
Thanks this helped so much.

+1984bobo49 Follow up - Drove about ten miles this morning. No stalling,no check-engine light, runs smooth as silk. Thanks again friend.
+1984bobo49 Proof for the naysayers.

Good vid,ima having a lil rough idle at start on my 94gt,just got a volt meter for 4 bux and im gonna try this out,im running a lil rich
Interesting tuning tip!! I was thinking you might want to index the sensor in case you need to remove it for some reason, that way you can put it right back into position without having to re-tune.
i can tell u everyone this works especially if u have i mildly modified mustang or 87 Lincoln mark 7 LSC
Interesting fix, is the maf sensor clean and within specs, this would account how the tps affected the performance so much.
great vid thanks
My 1990 Notch would not even fire with a bad TPS sensor....would start for a split second then shuts off. Installed new one and fired right up runs like a champ. Crazy it went bad in storage
Anything close but below, 1.0 will be Great. .99 will give you instanous throttle response. Anything close will be Fine.
Thank,
Keep on Dreaming
the information i have on the tps is 0.98 or 0.99 V with the engine not running or 1.03 1.05 with engine running
My 92 Idles fine has no problem revving from 1000 rpm on up, but it almost feels like it has to fight to rev right as I press the gas pedal from a lower idle. Is that the symptom you were referring to when you said "all of the hesitation is gone"?
I have an '01 Grand marquis 4.6L but using '02 Mustang GT throttle body, so what should the voltage on the TPS be, the same?
I have a 1993 mustang with a 306. what should i look for if/when i adjust it for volts? I am running 36-40psi for fuel. Many thanks.
Would this cause my GT 40 5.O shift too soon at 4000 rpms at WOT with an AOD transmission?
Es posible que subas el video en español para beneficio de muchas personas que tenemos mustang.gracias

set your timing to the 14°mark as well
Thanks

Bro, this guys user name should tell you all he knows about Mustangs.
.78-.99 is specs for factory.
Anything between 0.75 and 0.98 is good, under 1 volt!!! NOT over!!! Yours is too high!!=)
Thank I was thinking the same lol
i gained 12 rear wheel horsepower 🐎

Is your check engine light coming on? Maybe the thing is junk. There is alot of info on the net on this subject.

Dude just stop please...go over to Brew2L and watch his video on doing a base idle reset. You're killing this car!
This video has nothing to do with how the car idles.
Nice channel...NOT.
it looks like you live by me with your vid by the fair park. my car has not started in days. not sure why? could you help out? i'm the owner of swords & dreams on greenfield ave. my name is tom.
Is it turning over and not starting?
yes.
Oldsmob455 mine is turning over and not starting too
My 1990 5.0 mustang isn’t starting
you had it at .8+ just by turning it......
.98 is exactly where it needs to be lol
NEVER enlarge the slots! It'll cause the engine to surge or something. That can be dangerous!
Marty Stevens that doesn’t happen unless you tight the bolts hard asf
Marty Stevens also if there is a grounded wire and makes your battery gauge surge a bit, that can also be the affect
"oh it's spring loaded " 👀no shit Sherlock of course it's spring loaded how else is the computer gonna know the position of the throttle plate so it can disperse the right amount of fuel thus the problem lies somewhere else

Mr. Walsh, I didn't dream this up. I read it in the Mathis Mustang Performance Handbook.
Calm down killer. It also helped me out.
You are not adjusting a carb on 69 camaro. Its computer controlled, which run great when all the sensors are adjusted within spec. You just cannot adjust sensors and go by feel. You have to find what the correct factory settings are, adjust it to that and leave it the fuck alone.
The proof is in the pudding. When a intermittent CEL light gets fixed and there is more power I'm game. Do what you want with your car.
