1989 MJ, 4.0, 5spd, has been missing at all speeds lately. As per normal, block, head and valve cover areas nice and oily.
What I thought was oil at the exhaust manifold on the front-most cyclinder is actually gas. Pulled the plug and it was fouled with gas, checked the wire and it was OK, plug fires, too. All other plugs, wires, OK. Lots of carbon on the dist. cap posts, cleaned them, no change.
No smoke from tail pipe, backfiring, knocking and pinging or stalling.
Any ideas?
