hi everyone, i tried searching the forums and stuff, just so much to read but not much on my specific problem.
first off some info, 1994 4.0 auto 4x4, 320,000 km's,
started up fine, warmed up, hit the highway doing about 55 mph, got about 5 miles from home engine loses all power, i drift to the shoulder and it stalls. engine light comes on.
it restarts, runs very bad, missing but no back firing. i can keep it running by being on the gas but if i try to let it idle it slowly stalls.
i limp it home, shut it off and let it cool down so i can do some trouble shooting.
checked plugs, wires, disconnected the battery.
plugs and wires looked fine, so i reconnected the battery and started it. started fine, idled good until i put it in drive, then it started idling bad again.
i tested all the plugs and 2 out of the 6 are sparking really low compared to the remaining 4. thought it would be plugs but i switched them around and the bad spark stayed with the same cylinder with different plugs.
and finally plug wires are fairly new.
what would cause bad spark on only 2 of the 6 cylinders outside of bad plugs and wires?
thanks in advance...
