Hey everyone I still tinkering with my 94 4.0 sport 2 door 5 speed bone stock. I cut out the muffler and replaced it with a magnaflo. Sounds good now I also replaced the o2 sensor and the cps sensor. I only have 1 O2 sensor up stream. I cleaned the IAC sensor and throttle body. I just replaced the coil with a Accel coil. Runs alot better still have have a RICH smell . I checked the vaccum system and no leaks. I dont know how old the injectors are they look oem. If they are leaking would this cause this rich smell of unburnt gas? Just to improve the gas milage im thinking about replacing them with these. I drive about 30 miles round trip to work. Any other thoughts.

Well since i posted this I did find a huge vaccum leak. I didnt know about the canister under the bumper. Simple fix pug the hose back in. Also ordered the injectors. Installed them last night no more rich smell and runs alot better. Going to take it to emissions today.
