Did have 2 codes, p0132 and p0138. I replaced both oxygen sensors, that got rid of the codes, there are no other codes.

Yes. I also put a gauge on the fuel and it read 40lbs. I guess it should be 50 to 60. Do you think that could be the problem?

So you back pressure tested the exhaust and that checked out? Also so while your driving above 3500 the engine cuts out or the transmission is slipping?

No, I did not do that. And it is definately the engine, not the tranny. By back presser you mean, put my hand over the exhost and tell it to cough? Or is there a reading of some type tthat I need to get? Or change in idle, or leaks, or? This back pressure bit ive never done. And before I forget, thank you verry much for your time. Im sure theres other people that also need your help as bad as I do.

No a back pressure test is done with a back pressure gauge in the exhaust pipe.
