What causes a cylinder 6 misfire?
- Faulty spark plug wires or coils
- Faulty fuel injector
- Worn spark plugs
- Distributor failure
- Low fuel pressure
- Camshaft sensor defective

- Engine timing off
- Leaking head gasket
What is the cause of a p0302 misfire detected code?
A misfire is just what it sounds like; a cylinder that is not firing as it should. The P0302 code is caused by a misfire on the number two cylinder. The Misfire monitor diagnostic is based on variation in crankshaft velocity. The PCM determines this information using the crankshaft position sensor and camshaft position sensor.
What does engine code p0306 mean?

What happens when a cylinder 5 is misfiring?
Engine Cylinder 5 is Misfiring. When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position ( CKP) sensor signal to vary, the Engine Control Module ( ECM) can determine that a misfire is occurring.
What does the p0303 code on a cylinder 3 mean?
The P0303 code means that the cylinder 3 is misfiring or is randomly misfiring. Start by checking for intake leaks and if no leaks are found the next step is to replace the spark plugs on cylinder 3.
