P0302 on JEEP WRANGLER

"On march 13, 2010, my 2005 jeep wrangler displayed a check engine light. the code was p0302. when cleared, the code did not return and the jeep ran normally until approximately march 26, when it went into a "limp mode" (rev limiter moved to 2500 rpm) after being revved to 4500 rpm."

"Check engine light came on, with a p0302 #2 cylinder misfire reading. after replacing consumable parts (spark plugs, engine coil) reset engine light, the code p0302 returned after 15-20 miles driving. this issue is a well know problem with the 3."

"Check engine light illuminated, resulting in p0302 #2 cylinder misfire. after replacing consumable parts (spark plug, engine coil) reset engine light. code returned after 20 miles driving. dealer technicians indicate issue is #2 cylinder head needs replacement."

"Really have 3 issues with this vehicle. the first is that the engine began to tick noticeably at around 5000 miles, sound definitely coming from #2 cylinder. was initially told not to worry, noise was normal, oddly it did not tick previously."

"P0302 misfire cylinder 2. p0300, p0304 & p0306 jeep/dodge is very aware of this cylinder issue and has a service bulletin for several models. (journey, wrangler, 200/avenger, challenger, charger, grand caravan, durango and grand cherokee). and they will not recall this part."
