I have a 94' 4.0L V6... I've replaced plugs and wires about 15,000 miles ago, just replaced the fuel pump yesterday, I am getting great fuel pressure. Problem is sometimes it has a rough idle at start up, but the major issue is once the engine is hot and I'm cruising at 35mph it starts to "jump" like its a misfire same thing happens when I cruise at 45 mph. I put it in neutral while coasting and it revs up just fine, it only happens when its under a load... Any suggestions? I would like to get it fixed quickly for my brother-in-laws graduation present.
