After i left the code popped up again when i did a 60% throttle first gear pull and then when i shut off the car it went away. Anyone know if this is a spark plug and coil issue? First time i had power loss and second time DTMAL it was just the warning but car ran the same.
Try cleaning mass air flow sensors. They usually throw random stupid codes when dirty.
