I have a 2015 Spark, few days ago my check is engine on, after a difficult starting when refueling at gas station. After I got the code(P0496), I did some research. I suspect the problem is my purge valve is stuck open. The purge valve on a spark is really easy to reach, so I tried to take it off. I have no problem taking off the tube from charcoal canister, and I unbolted the valve from the intake.
The problem is I can't disconnect the electrical connector below. The white clip on the connector can slide up and down, but it doesn't seem to do anything. Has anyone unplugged it befo
