miss-fire problem - 8/15/2006 4:19:44 PM    rdwngs444   Posts: 5 Joined: 8/15/2006 Status: offline I've got a 2003 evo viii, and the service engine light turned on about 34,000 miles. the dealer said it was a random miss-fire code and the're not sure what the problem is. they won't work on it until its back to stock, i have blitz exhaust, hks intake, hks idling sensor, hks bov, and now recently installed turbo timer, and e-01 boost controller. still idles rough and miss-fires. ANY SUGGESTIONS? simply spark plugs, wires, or fuel? Post #: 1

There is a situation with the Evo having a missfire.....here is a thread on the evolutionm.net website: http://forums.evolutionm.net/showthread.php?t=88937 Here are the particular symptoms associated with this problem: It's a malfunction a portion of the Evo owners have been experiencing. It shows it's ugly head most commonly when applying light throttle in 4th or 5th gear at about 3500rpms. The symptoms of this problem include engine stuttering, inability to properly accelerate at light throttle angles and the appearance of the check engine light. < Message edited by XTREME -- 8/15/2006 4:25:30 PM > _____________________________ If it doesn''t spool it ain''t cool!!

If you don't have an Autozone there is most likely some small auto shop that will check it for near to nothing. The code should read P0300. _____________________________ If it doesn''t spool it ain''t cool!! (in reply to rdwngs444) Post #: 4

Did this start happening immediately after your boost controller and turbo timer? _____________________________ If it doesn''t spool it ain''t cool!! (in reply to rdwngs444) Post #: 8
