I have a 2004 Dodge Intrepid that pulled codes P0420, P0344 & P0340. I changed the plugs & coils AND the Cam sensor. Added fuel injector cleaner to the tank on fill up, immediately the engine hard sputtered on rapid acceleration. Took the negative cable off the battery for a half hour to reset the codes. Re-attached cable and drove the car about 1 mile and upon stopping the engine dies. Restarts and has a hard time continuing to run without having pressure on the accelerator. The engine light has not come back on, but I have not been able to get it up to have it scanned. Is there something else I can do that is obvious to anyone?
have the same problem?
