I usually get my CEL to start flashing. At idle or driving like a grandma it feels fine. When i would start to lean on it, the car would start to shake and shimmy like the engine ripped off its mounts and the CEL would start flashing. If i came off the gas it would drive fine and the CEL would go away.

check your fuel trim, mvb 32 in engine. possible maff problem.
