With key on, push off and warmer at the same time, on your climate panel. Hold them until all lights come on, release them, and codes will start displaying. You are concerned with codes starting with'P'. See if you can get a code and repost. Sounds like possible misfires from plugs/wires, and/or coils. Possible plugged exhaust, low fuel pressure. A code may or may not point to a so-called smoking gun. P.S. If it is a dual zone climate system, and the drivers side has a knob, the use off and passenger warmer. Fan up will select items, and fan down will scroll. Scroll until you find pcm, Fan up then scroll until you find PCM codes and fan up again.
