Ok so last week the CEL came on and I ended up getting the code P0304 which is engine misfire so, I changed both the plug and cop. Hisory back in December about 4000 miles ago did a complete change of plugs and cops. About two weeks ago after a 800 mile trip to the mountains and the car ran great. Then, last Monday night on the way home from work the CEL came on? Went to Advance Auto and got code P0304 - misfire in no 4 cylinder, again!. So, last weekend I changed COP and plug in no 4, made sure the spring was makng contact and applied dielectirc grease like before. Also, checked and cleaned all contacts to all of the fuel injectors and applied dielectric grease to contacts. Now, after driving about 250 miles and coming home tonight the darn CEL comes on AGAIN! Go to Advance Auto and no 4 cylinder is the culprit!! Again!! I'm totaly stumped. Any good sugestions? I'm at a loss here? Thanks again!
