If your sure the guage is good then you either have an issue with the regulator or the fuel pump.

Well, Murphey strikes again. Most of you've seen, Alabama got hit with snow and a little ice. Most of the parts stores were closed and the roads have been pretty jacked up, but I did get my cousin today, who happens to own a parts store, they are going to order the regulator for me on Monday and should have it in Tuesday morning so I'll pick it up when I get off Tuesday when I get off shift. I'll post and give the thread an update when I install it and see if that helps. Thanks for all the help so far.

With it running 35psi and running with the vacuum line off it was 40psi

Your problem isnt fuel pressure. Is it still acting weird at 3000rpm?

Yeah Que, as soon as it hits 3000rpms it's like it's on a rev limiter.
Just drove it around the loop and nothing's changed.

You didnt replace the intake air temp sensor. Its almost like you are running out of advance or fuel. I wish you had a noid light to put on the injectors. It would be good to know if the injectors are dropping out at 3000. The older engines had a wide open throttle switch that when it was pushed cut out fuel to clear a flood. The newer obd1 setup uses the tps and the ecu cuts the fuel. It sounds like what you describe. The fuel pressure would stay up but cut the injectors.

Ok Que, just ordered a new air temp sensor. I gotta work tomorrow and I'll put it on Friday and post the results.
Thanks again for all the help you and others have given me, just another reason I tell folks that Jeeps aren't just a car, it's a culture.

ok, installed the air temp sensor, hooked the battery back up, fired it up let it run for a bit, still cutting out at 3000rpms. drove it around the loop to see if it would get better as it got a little warmer, Check engine light came on and started cutting out at lower rpm's, got it home and it's over heating. inside temp guage never got above 220ish.
pulled the codes and im getting the normal 12, 33 and now a 22 is showing up.
Gonna run by the store and check on that noid light and check the injectors.

Coolant temp sensor? The only reason for it to light the cel is because it is out of range. It is the same sensor as the air. Spend the 20 and replace it.
