2001 Cl 3.2 Automatic Trans: Had performance issues, sounded like misfiring so replaced plugs and ignition coils... when started (cold) idled fine then began a cyclic revving between 1.5 and 2K then dropped back then revved again repeatedly. Once hot (fan motors come on) it tachs at 2k and holds. Taking for drive (under load test) vehicle wants to run away and have to ride the breaks. Heard clicks from engine mount solenoid so trouble shot that with no change. Anyone have a clue what can be wrong?
