Rev drops slowly from 1500 RPM after complete stop
Not sure when exactly did this started happening, but I noticed my car would stick at 1500RPM (sometimes 1800RPM - 2000RPM) after coming to a complete stop and thrown into neutral. After being stuck for a few seconds, it'll slowly drop back to the usual level.
Checked floormats and pedals already, not stuck at all.
Only recent happenings are installing my GMPP intake, replaced cat and water pump under warranty, and battery went flat and jumpstarted after I came back from vacation. Could the jumpstart of the battery messed up a sensor or something, or the cat failed again?
