I just got a 93 4.0 XJ and the previous owner beat it up pretty good. I have a few questions about it. How many oxygen sensors does a non cali 93 have? It is missing the exhaust from the down pipe back. It has one in the drivers side of the down pipe but, is there an after cat o2? Also anyone have a pic of the rotor button (cap off) with the motor at top dead center? I think the distribby is 180 out. It runs but smokes (black=fuel) BAD and runs rough. I am thinking it is a timing and o2 issues.
It could possibly be a bad map as well.
