I replaced those too. I'm starting to wonder about the computer now because everything I've tested had been working.

 

What brand sensors did you get? Reset PCM after installation?

 

They weren't bosh I have been told that they don't agree with dodge. They were ngk or something like that replaced both up and down stream. It's running real rich. Like I said before it runs almost normal if I unplug the pcv and give it more air.

 

Check your injectors then...... Got a scanner? See what the PCM is doing with short, and long term fuel trim. One would think that if the PCM thought the engine was running rich on a regular basis, it would at least have the decency to set a code.....

 

I ordered a scanner should be here in a few days. im going to break out my fuel pressure tester and test the regulator and the injectors today.

 

Have you figured anything out yet? I installed an air gap intake and my truck is running rich and misfiring on cylinder 2 and 4

 

I have a 2001 had the same problems. Rebuilt my 5.9 and still had the issue. Turned out to be camshaft position sensor.
