Check engine light is on. Obd 2 reads only error. Have tried 3 different scanners all say the same thing. Truck backfires like popcorn under load. If I downshift to raise rpm's power gains, popcorn stops. Idles almost perfect. No popping at all. Has new fuel pump 55-65 psi (fires and runs on a bump of the switch) and inline fuel filter, new spark plugs. Did remove cats due to they were stopped up. If I could just get the obd 2 to work I could figure out the rest. No blown fuses, power is on the #16 pin. I heard MAF sensor could cause a no read. Replaced multi function switch, I put in one without cruise control verses with cruise. Money was tight, would this have any affect on situation?
