how do i adjust my idle when the screw can't be turn??? do i get a new throttle body??? i have a A6 and i need to lower my idle to pass smog..

thanks H-T...

 

Take you throttle cable off and see where it idles if it drops adjust the cable.

 

thanks..that was the first thing i tried..but, i am using a dx throttle cable..but, i did it without the cable off and i had the cable loose while i was testing it.
i recently did a mpfi conversion..could it be my tps?? i haven't tried measuring the numbers though.

thanks.

 

have you swithcd your two out side wires on the tps. since you mentioned it.... check for vacuum leaks to...

 

the tps wires should be correct because, it's not at full throttle. i was told by the smog specialist that my idle was at 1800 rpm's. but, yeah i'm sure the tps wires are hooked up correct. and i'll check my vacums to make sure.

the car runs perfect, it's just that my idle is too high and i need to know how to work my way around to get that screw moving, that should be first and easiest way to correct my idle. but, again the screw is somehow seized or something. and the key to the screw same almost flat cuz, it slips right off everytime if i don't put enough pressure against it while i'm trying to adjust the screw.


thanks.

The idle screw on my car is the same way. I could never turn that damn idle screw

 

i wouldnt think that the idle screw would or could be that out of wack to allow it to idle that high. i would bet your problem lies elsewhere.
