'85 Vette Poor idle
Well I'm trying to help a person who has a '85 Corvette and is having a horrible time with an idle problem. Since my C3 is carburated, I'm not sure just how to advise on this issue.
The details as I know them are the idle is often very low and unless you're working the throttle it will stall. Hot and humid weather seems to make the condition worse. There are no warming lights either.This issue has made the car literally undriveable. Hope we can get this person pointed in the right direction and back out on the streets where Corvettes belong.
As a starting point I'm thinking a clean-up in the throttle butterflies but would anyone agree.
Thanks if you can chime in with some help!

make sure the throttle position sensor is calibrated right. It may be worn out and not giving a proper signal at closed throttle. Probably pull the throttle body off the plenum and give the entire thing a good clean and make sure it doesnt have excessive play in the bushings.
