    My 2003 Z71 Suburban's check engine light came on and gave a code for a random misfire. The tech at the garage recommended changing the Chevy fuel filter and Chevy Sensor I started off with the cheap route and had the fuel filter changed. It seems to run a bit better, but that could be because I have hoped that they fixed it. The code was reset and hasn't come on since.

    Talking to someone later in the day, they told me that GM had a problem with their fuel filters. Is their any truth to this?

    For that year? I've not heard about it. Had the code gone away for good?
