Trapper

A tuner, chip, programmer will cure the problem.

What CAI did you purchase?

You shouldn't be having a problem running lean with 97-03s..

Try cleaning your MAF sensor. Buy the tool and the correct cleaner and you'll be fine.



The oil from the filter may have got to the sensor. Read up on the DIY and handle sensor with CARE! It's a tiny little hair then wire and doesn't need much to break it. Should take you about 10 minutes.

Honestly, it's a win win situation! Easy to do and it does make a difference.
