Help with '85 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!

hmm, once my vette had some weird idling. When it was in park it would fluctuate from a little below 1k to a little over. It turns out the problem was a fualty computer. Not sure though, I'm not an expert. this was on my '90 L98.

EDIT: ow it also died a couple times while in park, but not too often.

I would check his mass air flow sensor to make sure it's functioning properly, and 
with the ECM statement above. I had one that was going bad that caused all kinds of weird problems.
