i have a 2003 3.1 and recently replaced the intake gaskets, about a week after replacing the gasket set the engine started running at a high idle 2500/3200 rpm. we replaced both the tps and iac. any suggestions would be greatly appreciated. im leaning toward a ecm problem.

Re: high idel problem

one other thing when I disconnect the tps the high idel stops and all is normal. i replaced the tps but it comes back when it is reconnected.
 
Re: high idel problem

Right...I think that has something to do wtih the high voltage issue. Meaning.. a TPS won't fix the voltage on the circuit. You need to investigate why that circuit is now high. Look for rubbed/pinched wiring.
