I have a 90 mj 4.0 renix still auto 2wd. Well on Thursday my distributor blew off of the block. Friday put a new distributor in everything was timed correct ect. It rilun perfect at idle but as soon as you put it in gear and start driving it starts sputtering mifiring and bogging down and such. Ran perfect except for a high idle from vacuum leaks before the distributer seized and blew off. A little lost. I'm sure it is something stupid that I miss but can seem to find it....any ideas? Thank you!!
