Back fire!!!
So My 88 cherokee 4.0 has been leaking out of the back injector. I replaced all the o-rings today and now the jeep is running worse than ever! It is barly running, back smoke is coing out the tail pipe, and it back fiered. It is not leaking fuel any more and I used dielect grease when I put it all together. Any Ideas....?

I looked at it and I see the vacum line still connected to the map sensor but, There is a line that is un-connected and it looks like it should feed into the throttel body. Is that the same line?
