Dukedog

I have 04 Silverado. The gas cap warning keeps coming on and the light turns on and off every other day. Gonna go down to Advance and see WTF is the prob. I think the sensor is slowly crapping itself. Went thru 2 gas caps. The first one worked for 3 months and then the light came back on. It stripped out and I replaced it again but the light is steady now. I will post what I find!!
