Any Idea?

Hey guys, So I started my car today and it was idleing at 2000rpm. It’s a daily driver and last night when I parked it everything was fine. Scanmaster said my TPS was at .76 but I had it set at .46. Could the TPS have just reset or moved? I’ve never had this issue before. If I unplug my MAF it brings the idle down to around 1100 but the TPS stays the same. That’s all I played with so far, I had to leave so I just took my motorcycle.

Any ideas??

Reset it. See if it moves around any by hand, reset, make sure it’s snug and see what happens. May be going out. May want to unplug ECM after before starting. Watch voltage as you go from idle to WOT (engine off) and make sure it’s smooth.
