Bad mpg's

I been getting horrible mpg in my 07 lsj. I have an zzp s3 with 2.8 and their crap tune, 2.5 dp. 2.5 catback. Cai

Sometimes when I get gas I go to start my car and it chugs and wants to die out until I give it some gas and drive it, then it's fine. At time it will read on the dic "check gas cap". Its tight and fine so IDk.

Any input on this?

I have very close to a similar set up. Everytime I got gas, my car would idle between 500-1500.. I replaced the Evap purge solenoid and it fixed that problem. As far as mpg... Can't help ya much there..

Sounds like Evap Purge Solonoid for sure.

Part 915 on diagram

Part# 12597567

Simple fix. I had mine do this to me 2 years ago. Everytime I would fill up with gas the car would stall. When I drove on the highway I would get random gas cap codes.
