ok i was checking some things on my car, and noticed it had an idle air control valve with the part number for a 94-95 camaro. i have a 97 camaro. i did some searching at work through some of our parts catalogs and found that there are two diff part numbers, and upon pulling both they look identical, and plug in the same and everything.. can anyone tell me the difference in these two, and if having the older style iac would make my car not want to idle? i couldnt find any differences to tell me yes or no.. thanks
