Need help with Idle Speed!!!
Hey! I just got my new 91' Camaro RS a little over a week ago and I have been having troubles with the idle speed. The car has a V8 5.0 Engine. When I first start the car for the day the idle speed will be running good at 1000 RPM's but the more I drive it the idle speed goes down to 750 - 500 RPM's and it sometimes will even go up to 1500 RPM's. Does anyone know what could be wrong.

Re: Need help with Idle Speed!!!
it is a TBI
750 is about the norm 500 is low is it a steady idle or does it surge?
do you have a check engine light on?
first i would look and listen for vacuum leaks then i would into cleaning the IAC pintle and oriface
