Ok so you remember my thread from before, well ive been to autozone, they said nothign was wrong, and i went to go to pep boys to have them check it but its 20$! and im not paying that ! so i was leaving the parkign lot at pep boys and what do you know, it starts doing it again, it revs to 1500 rpms and dies. But this time again i was revving it to 2000 for about 20 seconds, after that the rpm's stabled out at a little under 1000 (thats normal for my car) and i flipped it into reverse and as i left the parking lot the check engine light came on.. thats the first time that happneed and and i dont know what to do now... Ok so let me make that short for all who dont want to read it, Usually i start it up, it goes to about 2000 rpms and stablalizes itself under 1k and its fine, When this " PRoblem" Occurs it goes to 1500 rpms and dies to 0. You all said it might be Idle air control valve, Where is that located in car? i cannot find it. Also you said maybe fuel injectors, but im still waiting to get it tested, What exactly is that called by the waY? where i put the little computer on it to get the code? Thanks everyone, i really really appriciate all the help.
