My 1995 ford f 150 suddenly stalled when I was driving. It restarted and idles but bogs down when I press the gas pedal and dies. I replaced the air and fuel filters, the throttle positioning sensor and read the codes. I have an engine running code 311 which is thermactor air system inoperative. The air pump puts out air. I haven't tested the bypass and diverter valves yet other than to see that they have vacuum. Could the thermactor system be the problem or fuel pressure or maybe even a clogged catalytic converter?
have the same problem?
