Re: crazy idle issue 87 gta
Yes this is most likely a problem with your iac or tps. However, the first thing you need to do is take your air intake off and clean the throttle plates and throttle body REALLY well. These get extremly dirty on tpi motors due to the location of the egr valve. Clean your throttle first, see what that does, and then check your tps voltage and remove and clean your iac valve. Good luck!
