Hello everyone, my 2003 trac seems to be stalling out occasionally whenever im at a stop. If it doesnt stall out you can see the rpms dip low and my lights start to dim. I tried changing the IAC and egr valve but no luck. There are no check engine lights and this problem has been going on for months now. Any suggestions?
Edit: Didnt want to start a new post, but in continuation of the problem I finally got a check engine light today. Codes were: P0172 (System too rich (bank 1)) P2197 (02 Sensor signal stuck lean (bank 2 sensor 1)) Im guessing an o2 sensor went bad, but there is a problem on both banks which is what im confused about right now. Any help appreciated, thanks.
