xj_dummy Posted September 28, 2008 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.
mvusse Posted September 28, 2008 Posted September 28, 2008 Running rich may be O2 sensor. But then, I have no experience with the 2.5l.
BLHTAZ Posted September 28, 2008 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...
xj_dummy Posted September 28, 2008 Author Posted September 28, 2008 thanks for the tip. ill check on the o2 tommorow.
