93' Camaro smoking black, fowling plugs
I just bought the 93' Camaro, and the problem is it runs great after putting a new set of plugs in. Then after about a few minutes of idol it begins to smoke black , run rough, then knocks off. I look at the plugs and it is obvious that it is over load with gas. I want to change the ecm or computer but is this jumping the gun. It has a new fuel pump and coil pack. But this is all I know about the car. Motor sounds good until it fowls out. Runs strong but did notice it didn't want to pull in gear, another reason I beleive I should replace ECM. Anyone that has a suggestion I am open to anything at this point, as you know this part is expensive and I don't want to jump the gun if it could be something else.
