Title: Hunting at idle
Post by: Rholtby on December 09, 2015, 05:01:30 pm
Good evenin all,

So last week after filling up at my local esso garage, which I never do usually, my edition 30 started hunting and fluctuating at idle.

I've run the fuel down, topped up with she'll Vpower, still no change. Had it plugged into a fault reader and got given a few faults.

C0300
B2000

P0303 missfire no 3 cylinder
304 missfire no 4
302 missfire no 2

Ive changed the plugs as they needed changing anyway but not solved the issue. Any ideas would be great.

Thanks

So I've had a second opinion, after already changing the DV and putting new platinum plugs in, down at Colin Gunning or Hertford. They immediately knew the issue and confirmed my initial thoughts that it was the PCV. I've got the PCV and new gasket ordered into my local Volkswagen for tomorrow morning. Hopefully this will solve the issues

If your running a standard intake look very carefully for cracks underneath -  I've had more problems with air leaks causing these types of fault codes than the PCV :happy2:
