Swanicyouth Posted October 6, 2014 Share Posted October 6, 2014 Hi peeps. Was driving along and car starting hesitating and CEL came on. CEL stayed on - but hesitation stopped. Scanned the codes and got P0300 (random misfire) & P303 (misfire cylinder 3). Plugs were changed about a year ago with factory NGK plugs with no issues since. Reset light & went for multiple rides. After a while hesitation reappeared and CEL came on for a minute and went out. I ordered a new Hitatchi coil and NGK plug for cylinder 3. I'm wondering if anyone has experienced this and what the resolution is. I haven't received the coil yet - but I'm crossing my fingers it will resolve the issue.

CNAM Posted October 6, 2014 Share Posted October 6, 2014 Coil would be my bet. Definitely use the OEM Hitachi brand. Might cost you a little more cash. But will save you the headache of the problem returning. Link to comment Share on other sites More sharing options...
