I've had a problem with my 2001 chevy prism. I checked the engine codes and it was a misfire on cylinder 3. To eliminate the coil as the source of the problem, I swapped the coils from cylinders 2 and 3, then reset the codes and tried it again. The same code came back for cylinder 3, so now I'm thinking it could be an injector. I removed the fuel rail and injectors, then swapped the injectors for cylinders 2 and 3. When I put the fuel rail back on and started the engine, the car was blowing a significant amount of smoke, which it hadn't done before. I'm worried that something serious has gone wrong, but can't figure out what caused it. The car ran a bit rough before, but that was it. Now, it dies at stop signs and as I said, blows blue smoke. Is it possible that a small piece of dirt got into the cylinder through the injector opening and created this problem? I was pretty careful to keep that from happening, but I can't think of anything else. Does anybody have any ideas to ease my fears that I've wrecked a piston ring or something. Any help would be greatly appreciated.
