I have a Nissan Quest 99 SE with almost 170,000 miles on it. It has given me some headaches:
After I drove a little while, the Check Engine light would flash and, would usually stay on, occasionally off when it stopped. Using an AutoScanner it showed Code “P0306 Cylinder 6 Misfire Detected”. No more other code.
Taking the suggestion of my friend who works as a mechanic at a Toyota dealer, I swap-tested the plug wire to the #6 cylinder, replaced spark plugs (E3 E3.56 spark plugs. I suppose it should be better quality because it has longer warranty), replaced distributor cap and rotor. After finished this, when the engine started, idle was rather rough with the engine shaking quite a bit, and after driving it a little while, the MIL flashed again, but this time the Code is “P0325 Knock Sensor 1 Circuit Malfunction Bank 1 or 1 Sensor”, the Code “P0306 Cylinder 6 Misfire Detected” did not show up again.
I really don’t understand why it did not show up together with Cylinder 6 misfire at first place? Is it changing the spark plugs killed the Knock Sensor? Is it the wrong spark plugs? What else should I check or replace before I take it to the dealer? Any advice would be greatly appreciated.
