Ever since I switched to E85 I have been getting a message to Check the Gas Cap when I start my car. I am running this Walbro pump F90000274. Anybody else have this issue?

FWIW though my car drives very well on E85 with a pretty aggressive cam. I essentially have no surging on E85 and can cruise along in 5th and 6th gears with no issue running a 241/258 cam. It drives surprisingly well. For full disclosure, I am also running the Gen 5 Camaro 5 and 6th gears so it runs at a little higher RPM with these gears.

Replace your cap

I hope it is as easy as this, but I really asking if anyone else has gotten this error message after switching to E85. Maybe it is as simple as a new gas cap.
