Take it a shop or dealer that can "smoke" the system to find the leak. Just had it done at a dealer for $95 just for smoking. R & R of parts is extra. Mine turned out to be leaking gas cap.

How do you check the cap? Where do you get a replacement, if needed?
Thanks for any assistance, as our engine light keeps coming on and off, but no codes. Seems to happen soon after getting gas, so the cap is suspect.

Gearchatter has the best site for diagnostics of codes in plain English--about 1/2 way down in the boxes it describes simple things to look for and the most often causes---
A small vacuum leak is often related to an aftermarket gas cap--they never seal correctly as most are universal fit--get the correct cap from the dealer
