xj_dummy Posted September 28, 2008 Share Posted September 28, 2008 On the lil sticker under the hood says the timing is not adjustable. Is this true? Also It smells like my truck runs a lil rich too. How or what can fix this? I have changed the fuel filter, plugs, wires, cap and rotor, and air filter. Link to comment Share on other sites More sharing options...
mvusse Posted September 28, 2008 Share Posted September 28, 2008 Running rich may be O2 sensor. But then, I have no experience with the 2.5l. Link to comment Share on other sites More sharing options...
BLHTAZ Posted September 28, 2008 Share Posted September 28, 2008 Timing is not adjustable, but there is a tensioner in the 2.5L's that can go bad. X2 on the o2 sensor... Link to comment Share on other sites More sharing options...
