willow5 Posted August 9, 2017 Report Share Posted August 9, 2017 Hi all, I have a misfire problem with cylinder 4 (nearest to the bulkhead). I have replaced the spark plug but the problem persists. If I look at the engine bay at night when the engine is on, I can see a faint spark at the ignition lead tip (out of the metal can). I attach a picture but you need to look very carefully! This is visible from the lead while plugged into the spark plug. Please could someone help me with troubleshooting ? Quote Link to comment Share on other sites More sharing options...
