Car is 2002 GTP. Just replaced the LIM gaskets, valve cover gaskets, tb gasket and injector o-rings. the engine is now back together and it starts up and less than a second after she stalls out. disconnected the maf sensor and car runs but at very high idle (2500-3000rpm) and stays at that speed. cleaned the maf, same issue. replaced the maf, same issue. also changed the iac valve. no change. i was thinking a possible vacuum leak however i sprayed starting fluid all around the intake, s/c and throttle body and the engine did not surge up in speed. if you have any suggestions please leave them because i am at my wits end with this.
