Hi -

My pcodes are P0300, P0302, P0305 and P0306. But the catch is that there is a knocking sound that does not exist in idle but appears @1500rpm and above. It seems to appear from the right hand side of the engine?

Any help appreciated.

Thanks

the po300 indicates random misfiring and the others indicate where its missing at cylinders 2-5&6 [hmmm ''maybe the impulse sender ?]
