So my problem is very simple to explain and I am curious if any LNF owners ever experienced this issue and/or have any logical solutions. Whenever I get gas, no matter 87, 89, or 93 (always 93 but tried the others just to test), when I start the car up to leave the pump it cranks for maybe 5-10 seconds and struggles to start. Once started it has a rough idle around 900rpm and then it's fine when I drive away, start it again, etc. At first I thought it was bad gas or something but after a few times doing so I started to notice it was becoming a trend. It is a 2008 ss/tc with abount 21,800 miles. I'm probably going to replace the fuel filter tomorrow and try getting gas but it shouldn't need replacing with low miles like my car has. Any help would be greatly appreciated, especially so I don't look like a moron when I get gas in about a week! ~Jordan F.

Purge valve solenoid. Try unplugging the electrical connector going to the solenoid on the very front top of your manifold. It will have a plastic evap line running to it.

Are you adding more gas once it clicks? If so, don't.

It's definitely the purge solenoid in the engine bay

What exactly would I be doing tomorrow when I unplug the purge solenoid. Not quite familiar with this.

Just unplug the electrical connector on the solenoid itself. Then go fill up with gas and see if that solves your issues.
