I recently had my check engine light start to blink. Tested the code and it was p0300.
I changed the plugs, coil, icm, checked vaccum, fuel pressure even battery and alt.
after I changed the icm the car ran beautiful until I was in the drive-thru, the light started to blink again. As it is supposed to do, the engine went into rich mode ie. Trac off no power running rich. I am at my wits end! Any help in what direction I should go would be greatly appreciated. Also when it went into rich mode. It died and acted like the batt. Was dead until I jumped it.
