help with crazy idle on 93 si
I have a 93 si and on day it started surging while idleing. It pulses between 1500-35000 RPMs. I have checked the iacv, map, tps, valve timing, and all vacume lines. I am stumped!! The idle adjustment screw on the TB does nothing. The only way I can get any change is to retard the timing all the way and adjust the idle screw all the way in. Im sure the timing is straight. I love that it wont throw any codes so I have no idea what to do. Please help!! Oh yeah......Does anyone know what that sensor on the back of the intake manifold top right with the cap on the top does?? Thanks in advance!!
