Sitting in drive, ac on - runs smooth.
Sitting in drive, ac off - drops and recovers ~50rpm
Sitting in park ac on or off good idle.
It. Seems if Im in drive or reverse the idle is just above 500?
I have an obd2 scanner with live data (basic) and I find it weird that adding a little load makes her run great.
Was thinking of removing fuse for ac compressor as a next step.
