School me on evap and venting School me on evap and venting (1998 LS car)
On longer cruises to neighboring towns, my car will start to lose power and almost immediately die. After some troubleshooting it was determined that with the gas cap off or loose, the issue completely stops. Which created the fun issue of gas down the side of the car and bumper, lol. I determined it is vapor locking due to the creation of pressure, or the creation of a vacuum... not sure which.
Anyway... I'm currently running my return into the old evap line and evap is no longer installed. (Aftermarket rails and dual feed) Now I think the evap could be the issue but I'm not sure. The charcoal cannister hasn't been touched. I know the fuel hat has a vent line or something as well.
I know 98 cars are different than others but probably have the same principle. Feed, return, evap, vent.
Any pointers to get this resolved? Loosening the gas cap is not the answer. Lol
