Hey everybody im new around here. I have an 06 lsj pretty much stock right now. I do have a quick question though. I've had the car for about 8 months now and just had new tires put on for the winter and THE very next day i got this "check gas cap" light and then a check engine light. Had it checked and i think the code was P0455? Gross vacuum leak/ no flow and the "check gas cap" comes on every morning. I cant seem to figure it out any help is much appreciated!

 

Most likely causes (aside from loose gas cap) are either the canister vent valve or the purge solenoid. I would probqbly go with the vent valve

 

Where would that be located? Im under the hood right now

 

Never mind i found it, between the tank and rear axle but i didn't find anything obvious, pulled the connectors and put them back on see what happens
