When i start my car it'll jump up to about 2000rpm and come down very very slowly, and stit at around 1200 rpm when it is usually around 900-1000. Also when i shift it jump up alot more than it used to.

I can be driving in 2nd and let of the gas completely and it'll keep going w/ no slowing down....

Could my IAC be to blame for this ?

Also, sometimes when i come to stop my idle will drop to around 500 and barely run, then jump back up....

I already have idle issues sometimes because the cam, but not this strange.

start with bacis. MAF cleaning. vacuume leaks. did the problem just arise or did you take something apart and put it back together and have a problem (like i usualy do) hahaha.

you can try performing an idle relearn after cleaning the IAC....the problem you described sounds very farmiliar to a 94 I installed a tfs kit on and the only real way I know how to solve the idle issues that come and go after installing a stage 1 cam is to have it tuned out via a chip...they have chips like from SCT that'll address most of the idle issues you have

trying cleaning your iac or just go buy a new one. i had the same problem not long ago. i bought a motorsport iac for $85.00 at autopartsgiant.com. this is a very common problem on the 94/95gt with iac.

I dont think its a vacuum leak because my idle drops very low sometimes

I just cleaned my IAC about a month or so ago, i got it spotless.... I'll try cleaning it again and see if that helps out. If anyone has a link to a site with the procedure on how to "relearn" my idle, that would be greatly appreciated.

Thanks

vac leak... I didnt think I had any either... until I pulled my upper intake off and saw one of the lines completely disconnected from the intake

I'll check around and see if i can find one.

You still got those gauges for me by any chance ?

Well i just got a lil curious and decided to go out and look. I have 3 connections on the upper intake, one large one, and 2 small ones. The large one and 1 of the small ones had vac lines, but the other had nothing, i couldnt find any vac lines that were disconnected. I'm almost positive i put it on and just put a vac cap over it because there wasnt a plug supplied....So i'm guessing somewhere online the 700 mile drive it fell off somehow....I put another vac cap on and its back to normal.

Now i just gotta relearn my idle....
