i replaced the intake air temp and nothin changed, when i start it its just lik normal maybe it will stutter when hot but goes away in lik 15 seconds after starting. i havnt noticed any black smoke coming out when i start it , but i was driving it to the shop and my mom was behind me and she noticed it had black smoke and smelled really bad lik gas soo it wouldnt suprise me that its running a lil rich. but the coils are brand new and if a coil were to go out wouldnt it run bad all the time? and i have a new icm in it soo i now its not that either. i have the upper intake manifold taken off right now and i noticed a hose goin to the upper intake manifold was cracked and the hose clamp was not even tightend, soo maybe its that idk ill try it today and see if anything gets any better.... reply if you think of any thing new, your help has been much appreciated thanks
