Ba xr6t auto, pod filter (in original airbox) aftermarket IC, tow pack (which I hate).On start up it holds revs to about 1400 rpm, and only drops when in N R or D. When accelerating, it doesnt want to leave around 2000rpm, but will if you plant it. When the foot is then off the pedal, it will hold rpm (around 3500rpm) for up to 10 seconds before dropping to normal.Any thoughts? It has recently been serviced.
