• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Misfire Help Please!

very true, well I hope I don't have to take it that far but like u said I gotta keep diagnosing it as much as possible I'll probably try the sensors, throttle body screen and coil packs next I guess

Highly doubt it would be the screen honestly, one thing my dad did was when i had the car on he removed a wire at a time from the coil pack to see if they each had the same rythem of spark then put them back on, Personally i think it helps rule out the icm and coils at the same time.
 


ya personally I don't see how that screen could make all the cylinders to misfire that bad but I've been proven wrong before so ya I just wanna get this outta the way so I can continue modding, no sense in making it faster If it doesn't run right first
 
Lots of advice, I wouldn't do any of it until you no there aren't vacuum leaks. Vacuum lines have got to be the cheapest and easiest thing to replace and vacuum leaks will cause random misfires. I used a hand held vacuum pump and found almost every molded fitting was leaking a little, one was leaking a lot.
