In this video I get into a misfire and check engine light on this 1997 Nissan Altima. The misfire codes are P0100 MAF sensor, P0325 Knock Sensor, and P0304 Misfire cylinder #4. The engine also runs rough at idle. I go through the steps of it’s diagnosis, find the problem, and come back after the repair. The actual repair of this vehicle will take place in another video (next week), this video covers how I found out what was wrong with this Altima. Engine performance issues can be tricky to nail down but with a little time, patients, and some diagnostic know how, I’m sure you’ll be able to overcome any engine performance issue.
