Check engine light is on (sometimes it blinks). Truck has no acceleration. Foot all the way down. Acceleration does finally respond but only after a minute or so (dangerous on the highway when merging). Codes are P1131, PO301, PO302, PO303 (Autozone). Changed two O2 sensors upstream, fuel filter, air filter, DPFE sensor, Maf sensor, TPS sensor, plugs and wires.
have the same problem?
