Hey. i have a 92 f150 with the 300 straight 6. Last week i started it up after work and it started running really rough almost like its mis firing. when i give it gas slowly it with rev up but if i hit the throttle hard it will bog down and almost stall. I have replaced the idle air control valve, the tps, fuel regulator, map sensor, rotor button and cap, plugs and wires, and the fuel filter. What else could cause my engine trouble? Please help.
