I know you guys must have seen a million of these threads but I figured I'd ask n e ways.... I have my g/f's 91 accord (auto.) and I'm tryinta find the cause of the erratic idle... checked for vac. leaks (didn't seem to find one) now I'm going to check the IAC... any suggestions??

 

does it idle like your car is breathing.... up then down up then down... if thats the case then its ur tps...
