2000 Chevy Malibu 3.1 L V6 idle at 4000 rpm
I have a 2000 Chevy Malibu that just randomly
started idleing at 4000 rpms while in neutral and
park and its idles at 1500-2000 in drive and
reverse. I have already changed the air Idle Control
Valve and the TPS and it fixed my problem for
about 15 minutes. Please help
