My 95 explorer is dying!About a year ago we were travaling and the thing just quit on the highway, got it pulled over, started right up.Went fine for 3 months, then fuel milage started to go down, would quit when putting into gear,both hot and cold.Put on the obd scanner, eot and ect out of range, replaced sensors, same thing. put back on scanner, no problems come up but still runs badly.Changed fuel filter,checked fuel pressure, pulled cat and ran with test pipe, same problems.seems to run rich.Help!!!!
