hey i've got a 1990 dodge ram 50 which has the mitsubishi 2.4 fuel injected. I bought it and it seemed to me as if it was running rich. its smoking at start and heavily smoking if i dump the throttle. I replaced the plugs and wires, cleaned the cap and roter, changed O2 sensor, and cleaned the TPS. Still blowing black smoke and running ruff. Possibly mass air flow sensor? or ECU? has anyone had this problem with this engine? would appreciate the help.

Thanks Jesse
