sniperi311 Posted September 8, 2004 Report Posted September 8, 2004 ive got a 93 olds cutty with a 3.1 mfi, bascically whats happening it its stutters a lot, but it still goes when its cold, its mainly when ive been driving around a lot, i think its an injector maybe, my ecm isnt pulling up any codes, ive changed the spark plugs, wires, iac, air filter catalytic converter, and O2 sensor...emissions, i have no clue what goin on, its failing because of hydocarbond, unburnt gas, which makes me think its an injector, if it is an injecotor whats the easiest way to check on our cars, or if its a sensor which one do you think thanx Quote
pitzel Posted September 8, 2004 Report Posted September 8, 2004 Pull your newly installed plugs, look for ones that are severely carboned. If any particular cylinder stands out as being particularly bad, the injector could be at fault. Quote
