High idle on LT1
Hi guys, on my 94 Z28, the cars idles around 1500 rpm, cold or hot. I've checked the throttle stop screw that the tab on the butterfly linkage would touch, the tab is touching the adjustment screw. Guessing theres some sort of electrical idle control solenoid somewhere? Whatcha think guys?

ever clean your MAF ( mass air flow sensor). with a break fluid. after i got my 383 put in and a good tune , we found that the z's idle was still a bit high. took that off cleaned it, ran like a baby. hope i could help. let me know

if not a bad vacuum leak could cause a high idle. that happened after i took a little too much meat off of the stock TB
so check vac lines.
did you do anything to the car recently?
