I was driving yesterday and my check engine light came on. I took it to autozone and he said he was picking up a vacuum leak. He told me to check my gas cap. Which seemed to be on tight. Where do I start to look for this leak?

Start at the power brake booster and follow it around the motor.. If your 4wd it could also be the vac lines heading to your hubs and IWE solenoid... Vac leaks can be tough to locate...

Well a vacuum leak would be up around the motor. If you checked the gas cap that would lead me to believe it would have thrown a code for an EVAP leak. Do you remember the code? I posted in both threads you started... Didn't know which one you wanted?
