I have a 94 ranger with the 3.0 and 5spd tranny. The issue is low power/ bad mpg especially up hills, and occasional backfiring. Symptoms are Much worse in open loop mode. A quick rundown of new parts I installed on the truck: plugs, wires, cap n rotor, iac motor, fuel pump, both o2 sensors, all filters and fluids. Using a scan tool and or dvom I have checked: maf, iat, tps, coolant temp sensor, fuel injectors, and ckp. All emissions and egr systems are 100% operational. Im lost now. Any help is appreciated! (Im certain its a fuel/air ratio issue)
