2000 Maxima GLE Idle issues
Hello, I have a 2000 GLE with 83000 miles. IACV was replaced at dealer about 6 months ago (79000) miles. Symptoms then were an erratic idle that was unsteady. Dealer advised that the valve was sticking, there was no coolant leaking that would cause a short and fry the ECU. Car has been running great until about 2 weeks ago.
Current symptoms are that the car will intermittently idle at 1000 - 1100 RPM when I come to a stop in traffic or at a red light. The idle is always steady, just not at 700 RPM where it should be.
When I come to a stop and idle is at 1000 - 1100 RPM and I put into Neutral, RPMs will surge to 1500 - 1700. When I come to a stop and idle is at 700 RPM (where it should be) and I put into Neutral, it stays at 700 RPM.
Is this a bad IACV, or is something else causing this. Could this be the MAF sensor??
Any help is appreciated. Thanks
