Okay Please Help if you can please...
i have a Misfire that isn't going away.... ( cy 1, 2, 3 and a Random + incorrect air flow now)
7 shops and close 2 grand and Nothing yet...
Parts Replaced : Coils, plugs x2(contaminated), wires, injectors, injector rail line head gasket.. Now they wanna open up the Motor and re-time or check the timings...

After 2 days of looking online, It seems like "ICM" is a common problem when we have changed all this stuff. any Advice/Help would be Greatly appreciated! Ohh the Misfires aren't when i am driving highway/city, It is only comes back (engine flashes) when the car idles.. the sound of the misfire has greatly decreased.

Again, Thanks in advance for all your help guys/gals

 

Ohh, One last thing, It does have a custom air in-take on it. and the cooling temperature of the car is weird. it goes only one notch in NO MATTER HOW hard or hot the engine gets ( not sure if that's related to the misfires.. as i read something about vacuum leaks?)
