Stock 4.0 in my 88 XJ. Not sure what caused it, but one night on my way home from work it was running rough. It acted like it wasnt getting enough fuel, and it backfired twice pretty good! Almost like it had a bad spark plug and or it wasnt getting enough fuel. It also sounded different coming out of the exhaust. Like it had a mild cam. So changed the oil, plugs, wires. It seems to have helped somewhat, but still running rough. Also i noticed my mpg went from about 15 to 7. Now when you drive it, there is no smoke. If you rev it hard, or get on it hard, it blows black smoke. Smells like fuel. the best i can tell. What would be causing it to get to much fuel?
Not a bad convertor, as it was hollowed out when I bought it. It also has a new muffler, air filter, and fuel pump with filter. Also has 217,000 miles on her.
Any help and pics would be appreciated!
