dose any one know the correct voltage going to the map sensor because on my 89 camaro rs tbi i have erratic idol and my dad and i have replaced the iac and we are just trying to eliminate any problems any input would be great.

Thanks,
Mark

 

ok never mind I have figured out the problem and it's not any of the electronics on the car the Actron car scaner we're using made the idle act eratic and its never done that to any other car we used it on so that was odd so a note to any one be aware idle may act eratic with actron scaner hooked up.
