My 1993 ranger 3.0L 5 speed is running rich lost about 2mpd how do you lean it out
Maybe a leaking fuel injector. Make sure the air cleaner filter is clean or replace it.
That sounds like your a victim of winter blend fuel, a lot of the older vehicles will notice an MPG drop of about 2 per gallon. Make sure the engine is properly tuned and your filters are clean. So if there is no check engine light then that is most likely the cause. Note: some of the older rigs might benefit from advancing the base timing slightly but not more than 2 degrees and then you need to listen for engine ping, if any is heard then timing must be put back or engine damage will result.
