Engine runs like silk at idle. It has been raining heavily so possibly a coil? I do also have a tpms light on that won't reset, not sure if it's related? Thanks for any help!!!

Congratulations on the E86, they are fun cars.
The AC clutch does not cycle on these cars, stays on using a throttle suction valve to adjust cooling capacity.
Need a good BMW code reader and check for codes
