    Misfiring is back again on 2004 TJ

    I thought the documented crankshaft position sensor error code was P0320. This problem I have goes to P0300 then flips to P0302. I apologize all this is completely new to me and I am still learning.

    Well, I am back. I have now fitted a new ignition rail and new Autolite XP985 plugs. after 50 miles I have back P0300 that flips over to a P0302. Any more suggestions.

    Thanks. I have new plugs arriving Tuesday. Will try the tips and tricks above with a top end clean prior to replacing the plugs. Is it worth spraying some CCC in the plug holes when fitting the new plugs? Thanks all for your help, I have learnt a lot.

    My misfires get worse though as the engine warms up and after roughly 50 miles each time. Is that the pattern with plugs? They run fine up to 50 miles

    Had a P0304 problem and changed ignition coil rail and plugs now it’s back as p0302, but I noticed it only happens when running after 50 miles, so when warm. Engine seems hot but not hot on thermal gauge on the dash. When vehicle starts from cold it runs great. What’s next fuel injectors?
