    Check compression, swap coil to see if misfire follows it!

    Check compression on 6 and compare to another cyl. that is ok! See if #6 plug is wet.

    Now we need to know what the compression is! Possible camshaft or follower problem. Slight chance injector but not likely. Post results later.

    This is on top of the engine, (cam and lets 'say' rockers) if this is the problem it can be repaired without much trouble, however all we can do is offer some possible causes, which could be wrong. We will know more after comp. test. Intake valve has to open for proper compression, got to have air to compress, may be the trouble and tapping noise due to follower problem.

    I agree with wetry we need to know if the cyl has compression to further diag problem could be a bad injector
