1988 xj,cyl#s 2&4 fouling plugs ,big time.my guess is it's getting oil in the airbox.this is not my xj but i,m putting a bumper on it today.anyone have thoughts on the plugs problem? :roll:
i would look at the wires cap and rotor. Make sure the plugs are firing good. Wires are a big factor, i have seen them deteriorate from the inside out.
