My 93 4.0 seems to be running rich, plus a. lot of exhaust fumes in cab. The fumes are enough to get me high. I have all new exhaust system and have checked and rechecked for leaks. Tailpipe does not extend beyond the bumper though. Thinking about an extension?
Aside from it getting in cab it smells very rich. It has been fully tuned. Using Autolite 985 plugs, maybe go to a hotter range? I pulled #1 and it looks fine (clean burn).
I appreciate and all advice.
