Hey, i got a check engine light and went to autozone to hook it up to the computer, and it said "EGR valve insufficient flow"; the truck runs fine, i was just wondering if this was something i need to take care of now or can it wait till the weekend (the truck is still under warranty, so i'm not worried about cost). as far as i know all the egr valve does is pump exhaust gases back into the intake, so i'm assuming the truck will be fine with it not working (may even run better?).

thanks for the info folks.

 

I did exactly the same thing you did and the Ford dealer said it was ok to drive until they got the new sensor in (5-14 days).
