Yes, I replaced both crank and cam sensors. So that would be it - the procedure which I suspect is the cause of why I can't get this engine to run right. It's got a 0300 misfire code. It's not the spark plugs, wires or coil. All of those were swapped out and checked. I checked the cam sensor and that's not it. I can't put back the crank sensor as it was bad to begin with. I can use one from my other car. We own an 05 and 06 Aveo.
