If I can't figure it out tonight she going to the dealer.... When I start it it will run then it sounds like air backfiring in the engine and it stops. Runs hot but plug color looks good. No throttle at all revs a little but in gear if you floor it it barely moves. I checked the compression and got 125 but what is the proper way to check it? Turn the motor over once or kick it like your starting it? Could it be electrical?
