    Is it similar to when you unplug the maf sensor and try and run it, or could you unplug the maf sensor now and see if it runs the same way?

    Anyway you can get a scan posted up when it does it/low idle? Could it be the rear 02 sensor sim.? Mine went out and will cause the rpms at low idle sometimes they will rock the rpms back and forth from very low rpms to about 1200 rpms, back and forth...

    I'll try unplugging the MAF tomorrow. Rear O2 sensor is non-existant and it is turned off in the PCM, been that way for a few years.

    Well, that might be your problem, they say on most 01+years the rear 02 just can't be deleted from the pcm. On my 01, i tried deleting the codes and still had the problem.

    Read through this and see if it might be the issue:
