2003 Nissan Altima Question: Cylinder 4 Misfire
I recently had my check engine light come on and after getting the code checked it was determined it was the camshaft sensor. After changing the sensor, the engine light remained on and will occasionally blink. The engine code now is P0304 (Cylinder 4 Misfire). I was wondering where is a good place to start in solving this problem and if it is safe to drive while I diagnose the problem? - Visitor
Continuing to drive a misfiring vehicle can damage the catalytic converter, so it's not a good idea to drive it much. If you cannot determine the problem visually, try swapping the spark plug to cylinder #1, the coil to cylinder #2 and the injector to cylinder #3. Erase the code, drive it and when the light comes back on, and if the code remains in cylinder #4, you just determined all those parts are OK, and the problem is in the cylinder. If the problem moves to another cylinder, then the part you moved is faulty. - Bret Bodas

Hi, I've been having trouble with my 05 Altima. Periodically, the SEL will blink and the car will start to shake and shimmy (misfire). It will do this for 2- 3 minutes then suddenly stop, the blink...
