This was definitely my issue. I just went ahead and bought a coil same day delivery today, and I switched them around until I found the bad one. It was the second one, 2 and 5. Now it's running great. It was getting very bad, not wanting to accelerate sounding like a grinding machine gun. Now I can gun it up to 60 pretty quick no issues! Thanks so much for this!

check your plugs and wires first then work your way down to your coil pack then the module,if all else fails try a fuel pressure gauge,it also can be the fuel the older the car you need to run a higher octane fuel like mid grage

I collect lesabre cars my daily is a 95 model. 209k and still going. I got a 05 lesabre not has a 0305. After i cleared up the p0300. Ignition control module is next. Plugs wires fuel filter. Changed.
Some of the best cars ever made imo. I have an 04 Lesabre as well (currently needing a trans 😢) Thanks for watching and for the Subscription. I appreciate it!
I have an OTC hei spark tester like the one you have. While the minivan is parked and engine running (idling) I was thinking about accelerating the engine speed to see if the misfire reveals itself. If the misfire doesn't reveal itself with that option, will it be a good idea to do a brake torque test to see if that will reveal the misfire? I will be doing a cylinder drop test using a test light while removing one wire at a time from the coil pack for both options. Should I use the test light when doing both options or the OTC hei spark tester?
Well done I’m having same problem with my 05 the 2 and 5 coil pack wouldn’t spark . Bought new pack and the car won’t even start now. My next step is just getting new coil module
I thought I may have been heading that way. Make sure you don't have any corrosion on those module connections. I've fixed one in the past and that was the issue.

@@HowIDoItFaM thank you for the quick reply. I don’t understand why it won’t fire now when I got it home and shut it off it would start up then. Maybe cuz it was still warm idk. So much for an easy fix I thought lol. Thanks again I subscribed to your channel
Sounds like it could be a loose connection somewhere. I remember running into that in the past and one of the spark plug wires had Rubbed on something making it short out sometimes.
Man i have a misfire and have for months now..ive changed wires the plugs the ignition coils the icm module the cam sensor and crank sensor and i still cnt figure it out its a head ache..i jus got another code fuel injector number 5 replaced that and it runs a little better but not like it should ..and its a 06 buick lucerne cxl 3.8
It's almost impossible to diagnose something like that since I'm not there in person. You've changed most of the main components in the ignition system already out sounds like. When you changed that injector has the code returned? It possibly could be be a dirty fuel filter, or a bad fuel pump. I've had a semi functioning fuel pump that have new misfires like that. The other culprit I've seen is a slipping timing belt.
Yea I have changed out all ignition related parts .it's been kicking my azz too and hurting my pockets..the code hasn't came back on since I changed all of the ignition parts and the #5 fuel injector I also cleaned the other injectors and made sure the spray patten were a fine mist not a drip or dribble and they all were not stuck and fine..But although no check engine light has came bck on it just still feels like she isn't all the way bck to 100% ya know ..its like chasing a ghost..I just want to find the culprit ya know..
4 and 1 coil pack keep loosing spark? All coils new and board. I'll swap one out and it will spark again. Anyone got an idea of what's causing coil pack 4 and 1 to act up?
Have you changed your plugs. I know sometimes fouled plugs on these cars can cause strange things. If it the plugs are good I would look into the coil module. ( I can't diagnose since I'm not there) but I'm leaning towards it being that coil module.
98 lesabre. Mine was replaced not far after 100,000 miles.ecm(computer in engine covered) soon too.car just shut off driving one day few years ago.mechanic replaced it. American cars nice ride...but need wooden always. Toyotas far outlast any American car.

I have a 2003 DODGE CARAVAN SE V6 3.3L The minivan is giving me a P0300 code. I turned on the engine and left it idling. Connected a test light to a ground and connected a vacuum gauge to a vacuum port on the upper intake manifold. I did a cylinder drop test using the test light while removing one wire at a time from the coil pack and observing the vacuum gauge needle for movement. As i was removing one wire at a time from the coil pack using the test light the vacuum gauge needle was not moving so i can know which exact cylinder is misfiring. Do you happen to know why the vacuum gauge needle was not moving? I uploaded videos on my channel so you can see the tests i did can you check them out, please?
Could you tell if it was misfiring while you were testing it? I mean audibly or visually. Sometimes those dang codes pop up with intermittent faults, which sucks for us when we are diagnosing it. It may have not been exhibiting the fault while you were testing it.
@@HowIDoItFaM I couldn't tell if it was misfiring when i was removing one wire at a time from the coil pack. I want to find this misfire so bad. Today i was in a parking lot parked up and as the minivan was idling out of no where it completely shut off on its own.
@@AlwaysDiagnoseVehicleFirst ahhh got ya I see what you mean. Now that is odd you had the wires off and couldnt tell if it was missing. Let me ask you this. Do you have a code reader?
@@AlwaysDiagnoseVehicleFirst that's a good one. P0300 makes me think that it could be something electrical since it's not specific to which cylinder is misfiring, because if you had multiple misfires at the the same time you would definitely be feeling and hearing something strange. One way you could test it is by removing a wire and check the codes and see if it gives you the specific code for that cylinder.
It's hard to diagnose since I'm not there in person. Could display a number of symptoms though. Complete no start is one, it also could display the same symptoms as bad ignition coils. First thing I would do is to check for spark at the coils. Does even attempt to start? A sputter? Back fire?
Dealing with a crank no start. I know I got fuel to the Rail (the fuel pump runs and the Schrader valve squirts fuel), but no spark or no potential injector pulse. Can I use this to verify a no spark?
@@HowIDoItFaM okay. Was gonna say I just took the wires off the bottom coil pack.. crank.. nothing. I put those back and take off the wires at the middle coil pack.. crank.. still nothing. If I removed the wires from a coil (kinda like it is in your thumb nail) would spark still jump across the towers
You should see at spark at that coil with that wire off ( I wouldn't recommend checking it like that without tool) even still you should see spark at the coil. You have some one that can verify if there is spark at the coil with the wire off?
@@HowIDoItFaM yeah I had my roommate check it for me. I removed the #1 spark plug at the tower to see if spark would bounce off the tower and the coil pack. No dice So I removed #1 and #4 wires (basically the bottom coil), no spark jumped between towers. Remove the wires from the middle coil and again, no spark jumping across the towers. Needless to say I'm in for either a crankshaft position sensor or a ignition control module. Luckily the ICM is easy and cheap to replace
Yep I just about to say sounds like you might be looking at a icm... I know sometimes the connections on the icm can get corroded, so check that out too.
Your videos help a lot. I have a 2004 park ave one day it was having trouble starting but ran good once it started. Few days later I started it and drove it like 25 ft and the gas pedal wasn’t accelerating at all. I tried to put it in park and restart it but now it just doesn’t want to start. I replaced the fuel filter and fuel pump and check the fuses. You think it can be my coils?
Without checking it out in person, it's kinda hard to say. Since you've already changed a few things it's possible it could be your ignition module its self. Here's a link to what it looks like. www.carparts.com/details/Buick/Park_Avenue/DriveWire/Ignition_Coil/2000/KIT-082516-16.html?TID=gglpla&origin=&&&gclid=CjwKCAjw6IiiBhAOEiwALNqncaP3pHAUzDe1g-YkOu-cEeudz859u1lSEgh5yMUu2QETe5xkOQI_XxoCHbQQAvD_BwE&gclsrc=aw.ds This is what the coils connect to. Before changing it though make sure you have the coils and wires connected correctly and corrosion free.
Could be injectors. I would definitely rule out everything else first. I actually had a lasabre that misfired because of a bad fuel pump. It wasnt pumping enough fuel. A fuel pressure test could rule out that.

After changing the coils, you should drive the car at highway speed for a while to burn off fuel residue in the catalytic converter.
No doubt about it.
