still have code 25

Since you live in the valley, I wouldnt worry too much about it. I don't know that if the PAIR was not working that it would affect the O2 sensor reading. I was just speculating. I would check the AFM and O2 sensor like previously stated. the 22r still has the PAIR and EGR and all that stuff, it may just be set up a little differently. Personally, I think its a good idea to keep that stuff on because the engine was designed to run with it.

i replaced the o2 sensor today still no change. do you know if the afm is the same on the v6 trucks i got a friend with one i was gonna see if we could swap out and see if it runs better, and ive just heard the 22r has less problems but i dont know if thats true but i plan on keeping this truck till its dead by the way things are going it problably wont be very long haha

This is the FSM procedure for testing the airflow meter on the 3vze....

If you don't find any problem there, try running a test this way....

You'll need an ohm meter if you don't have one, though. Testing with one for this part is rather simple and easy. Just connect the pos and neg probes to the designated terminals on the AFM and record what the meter reads. Then, compare to manual specs. Of course, there won't be specs in the manual for the second procedure in the thread. But, that is explained.
You're bound to have problems on an older vehicle whether it's a 22re or a 3vze. The parts, particularly the electronics, wear out. I've worked just as much on my 22re as my 3vze. Compared to other vehicle manufacturers I've had, though, I'm not complaining. 200k better than 50k or 100k.
