Engine Performance problem
2003 Pontiac Aztek 6 cyl Two Wheel Drive Automatic

have a 05 Aztek and it has recently started idleing at 1500 in drive and 3000 in park. I have replaced the Throttle position sensor and that has not fixed the problem. Any suggestions that could help? Thanks in advance.

Check your manifold pressure sensor located atop the intake manifold. It is hooked up the the fuel pressure regulator via a t-conntector hose, so becareful and not pull it to get it off but rather use a screwdriver to pry it off. Also if any codes scan for them at local parts store.
