I have been fighting a few issues for a while now and need help with a new one.
92 4.0 ax15 100k miles
Started as: Stutter/stumble after each fill up. Fix=Fuel pressure regulator (jeep would run great when I plugged off the vac line from old one)
Stutter/stumble after 3 hours of serious dune bashing. Fix=TPS (old one shot bad...another great write up that I found on here)
New problem = running way rich at idle, smell fuel, sprinkles fuel out of exhaust, completely blackened new plugs in all cylinders after only 10 minutes at idle. Sounds like it is missing, but only every once in a while. all at idle. Not sure that I want to road test it until I can find a solution.
This came immediately after changing plugs and wires. Cap and rotor were installed prior. I inspected the Coil and discovered corrosion on the tip...here is where I may have gone wrong, I used sand paper to clean it up. Not to rough, but could this be what is causing my issue?
Thanks for all the help, you guys have kept me in the dunes out here!
