my car runs great cold but when it gets warm and changes loop it runs terrible like a miss and a lot of knock.. just looking for someone local to help me maybe scan it when running hot so i can see whats wrong also runs rich and blm go to 108?maf..?
fuel reg..? opti..? icm...? help!!

 

I would look into the fuel system first, throw a fuel pressure guage on your schraeder valve, and see how many PSI your running (Should be ~41-47psi at static/KOEO (Key on engine off).


First off check that, change your fuel filter if your pressure is low..If your pressure is fine, I would look into a coil. If that doesnt work, try an ICM...I JUST went through this problem and it turned out being my fuel pump. Only mine wouldnt start when it was hot after I turned it on.

 

when you firt start car fp is at 43.5 vacum line on new fuel filter, new coil ,tryed old coil same difference. when i koeo pressure goes up to 49 then to about 32 but once it startes goes up to 43.5 cold but when the car is hot the pressure usually goes down to 36??
