DTC Questions 1131
My check engine light has been on about a week now with no differences in performance. I pulled the code 1131 which gives a several possibilities. I noticed right before the light came on and after I got the light turned off while going "WOT" is when the light came on, but again no differences in performance.
One more thing, when you undo the cap and look down the filler, there is a thin metal "flap" which I assume is for splashing and backfilling of the tank to prevent overflow out the neck. My flap is completely gone. The previous owner somehow messed it up. It sucks whenever I'm filling the car up the gas pump will stop every few gallons, but anyhow could this be causing the issue?
Thanks for all the replies and help!
