i have a 2002 gt pretty much stock just exhaust and intake.......needin some help on this one. i have a popping noise coming from the motor while at idle and a shutter while maintaining speed at low rpm's. sounds to me like its running lean. any help?

i have a feeling its coils going bad or clogged injectors, i have 87000 on the original coils and injectors, plugs were just replaced 10000 miles ago, i cleaned the MAF sensor, and the IAC valve, but it ran the same after, but noticed a lot more power after cleaning the maf sensor. i just ordered new coils tonight well see what happens next after i get them installled

i replaced the coils tonight, i still have the pop sound coming from the exhausts sounds like a missfire, im thinking clogged injector somewhere maybe? anyone have any idea?

took a look at the plugs. ton of carbon on em. i think i had weak coils which resulted in carbon build up on the plugs. off to get plugs in the morning. i'll keep everyone posted on if it was fouled out plugs.

turned out to be bad plugs. im guessing i had weak coils to begin with when i changed plugs last time about 10000 miles ago, which resulted in so much carbon build up. but the stangs running like a raped ape now
