Damn idle. IAC/TPS problems? Idle screw? Help!
Hey guys, long story short, 2 weeks ago my car was idling way to high, before replacing things I messed with the idle set screw, which I am now 100% regretting. Well I had to change my IAC. After changing my iac I did the whole idle re learn procedure, as well as following cliffys guide to setting the TB idle set screw..well the problem I'm having now is my cars idle seems to be working JUST on that idle set screw, I'm idleing about 800-900 rpm, but when I unplug the IAC at idle NOTHING, when I unplug the TPS at idle NOTHING!! my IAC is 2 weeks old..I can unplug the hoses going to the IAC at idle, NO DIFFERENCE. What the hell is going on guys?! Its driving me crazyyyy. When i put my A/C on the idle dips down to like 600 and stays there!!! Wtf. Its like the TPS and IAC are bypassed somehow? They are both literally doing NOTHING for my idle, and whenever I use any accessories my idle just dips and stays there, it will not come back up until I turn that accessory off! Arghhh, this Fin car lol.
