88 cherokee running rough need help!!!
I have a 88 cherokee 6 cyl. 4.0. and it recently while driving it just stopped running. all the electrical componets stayed on but the motor just shut off and wouldnt start again. so i checked the fuel pump thinking it wasn't pushing fuel through and it was working fine i just replaced it a few months ago. so then i checked the relays. they were fine also. then randomly after a little prayer it started. but it was running rough. almost as not all cylinders were firing. i did a couple basic checks and it started to run smoothly. then i noticed a small fuel leak coming out of the fuel pressure regulator coming out on the fuel line part. just as a precaution last night i changed the oil and flushed the cooling. and it started running good. so today i replaced the pressure regulator and the o rings and once i did that no leak but it was running horribly acting like it was missing during idle and no power when stepping on the gas and it was wanting to stall out again during driving. so my question is where should i start next to solving the problem i got new spark plugs but it didnt seem to help the problem after putting them on. any suggestions on what else could be the problem and maybe how i can fix it.
