Power Problems

I have a 2003 Saturn L200 and we have had some power loss problems. When the car is idling the tack bounces around and the car shakes. Almost like the car is not getting enough gas. Also with acceleration we have power loss. The car will not have full power, and it will shake. Sometimes it almost sounds like some small backfires. The light that looks like an engine is on, but when we have power problems the light blinks. The book said this is a sign of miss fire.

I have changed the fuel filter, put gas antifreeze and water remover in, drained the gas tank if we got bad gas, tried to find all vacuum hoses and check them, and took all spark plugs out and cleaned them. they did not look bad, but had some black suff (carbon deposit) on them, And none of these help. :banghead:


Had anyone else had this kind of problem? :cwm27:

the engine picture is the check engine light, and yes flashing means its a missfire. the best way to determan the problem pull the codes. many part stores will do this for free.
