It started to idle irradically and it spit out a code for misfire cylinder 4. was told to replace plugs, wires, dist cap and it would be ok. did all those, it started doing this again. te whole car shakes and it has no power. I replaced the camshaft sensor, the pcv valve, fuel regulator, fuel filter. I dont now what else to replace and Im tired of guessing. i took the car to a saab dealer and they could not tell me what was wrong with it. It seems like the engine is not getting enough fuel. The fuel pump seems to be fine.
