SOURCE: Have fault code P0302 on 2001 VW Beetle. No it is

this car has what is called coil over ignition which means no plug wires or cap so if it is missing swap coil from cyl 2 and any other cyl then clear code and rerun car till light comes back on then check code if it is still cyl 2 missfire then replace that plug if code changes to the cylinder that 2's coil was on then replace that coil <that car does have a recall for coils> if car is not missing and you have that code most likely isnt an ignition problem but will have a small vaccume leak so check the small hoses for leaks. very common for fuel preasure regulater vaccume hose to brake from age

Have you tried new Spark Plugs? Also after removing the plugs.
Take a paper towel and roll it up so it is like a long thick pencil. Stick that down the hole the spark plus came out of. Just to clean the moisture out. Also blow some compressed air down the hole.
Make sure all the moisture is out. The put the plugs in.
When you wash you car. Be careful if you wash the engine.
Dont let water get in to the plug holes..

P0302 - Cylinder 2 Misfire Detected,what needs to be done.


Fritz, Clear codes, Plugs and coils try switching them around, not using the same cylinder, to see if code changes to different cylinder. this would help diagnose bad coil or plug. See links below for full instruction. I have had this code come up because of a bad/dirty fuel injector also. Last link tells what other reasons code could be thrown.

How to repair a number two misfire


ok you have P0302 DTC errors. why not POST ALL ERRORS?

P0302

means that cylinder was weak, (NOTHING MORE)

caused by 4 things.

1: bad spark (even spark plugs, ever do a tuneup, BAM , easy peasy)

2: bad compression, (a tests shows 150 or more on #2 and it\'s ok.

3: bad fueling (tool lean or too rich) the real scan tool shows you which it is , did you look at fuel trim and make sure closed loop works at idle and light 40mph cruise (flat ground)?

4: water (coolant) is leaking into combustion chamber.



there are the 4 clauses.



#2 cyl. misfire.



no engine ever stated of the many, opted. so ?????? answers.

After putting gas in my car, why did it start shaking really bad and idling real high?


After a fill up, the fumes in the gas tank are very concentrated. If problem with evap system, it could cause problems after a fill-up. Just a thought.
