ozzyboy Posted November 12, 2014 Report Share Posted November 12, 2014 pull the leads off one at a timeif theres one or more that don't make engine run any different then that's a good indication which cylinder the problem liesif that doesn't make any difference then take plugs out they should all look the same,if theres one that's say covered in oil or looks a lot lighter than the other that could point to the faulty cylindernone of that works do a compression testsmoke test to check for leaksthe list can go on and on Quote Link to comment Share on other sites More sharing options...
