HI there,
wondering if i can brainstorm what up with my 2000 XJ8. 94K miles.
after its timing belt change it has been running rough.
sometimes missing in multiple cyclinders resulting in engine codes.
have had the dealer check the plugs, coils, timing, fuel injectors, o2 sensors...
but all are reportedly fine.
currently its running rough but no check engine light.
they are stumped.
The only other things they can think of is catalytic (but they sound fine and there is no code for that) Or the ECU is bad (no code either though)
any other advice out there?
