      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?

      Possibly your fuel pump, it's working but weak.

      I replaced my fuel pump about 2 years ago... could it have gone bad again?

      Mine had the same problems, I followed what swshawii said and WALA my idling was fixed. The little rubber PVC elbow on the front passsenger side of the engine gets dry rortted and cracks, usually on the bottom where you can’t see it. I went to O’Reillys and they had one in stock for about $3 it fixed my issue. Good Luck with yours

      If you PCV hoses/elbow is okay, it could also be a bad IAC valve. It controls idle.
