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.

Hi,

Have you checked diagnostic trouble codes? I ask because this could be related to a plugged converter or a timing differentiation between the camshaft and the crankshaft.

Also, I have a favor to ask. I need you to start a new thread because of the different model year. We try to keep them the same, so they are more helpful to others. I hope you understand.

Here is the link to start a new post:

let me know.
