I own an old 87 Jeep Cherokee "limited"(it really is) with 100k on it. Straight six 4.0 injected, automatic. For the last few weeks it's been having misfires (no backfires) and trouble staying alive at cold starts, which lasts about twenty minutes. It also does this at warm starts, but reduces in extremity faster than when cold started. If driven, its chugs and hesitates under load, acceleration, etc... It intensifies if you're cruising at low rpm and lightly increase the rpm towards a down-shift. It bucks worse than my last girlfriend. If it is running in park and as the motor is quickly revved up and quickly let to go back to idle, the motor almost stalls out and has trouble finding its idling point. I've replaced the fuel filter, checked all fuel injectors and have changed those deemed to be too old. I've checked the distributor cap and replaced all plug wires. The plugs are Bosch and were replaced 5000 miles ago. The fuel tank is full (I'm not a complete moron) and doesn't seem to be vapor-locking. It's not causing any more motor noise and seems to be in the fuel or air induction system. Any ideas of what this could be?

Did you check your fuel pressure ?Fuel pumps do fail.
Is your Check engine light on,check for codes could help you speed up you diagnostic
for a faster repair
when your engine starts to play up is the Rev counter also playing up
You could have a bad crank sensor which is a very common problem
with the 4.0L .
