    Has anyone experienced any vacuum leaks near the throttle body. On my 02 GT is looks like there is a vacuum hose connected to the throttle body that then splits off into two hoses, one going to a tiny black canister and another going to another device. It looks like it is starting to crack and I am throwing this code but not experiencing any idle problems. It has been suggested that the fuel filter might need replacing. Any thoughts?

    Fix the known vacuum leaks first. Always fix known issues before you try to diagnose anything else in the system.

    Fuel filter is possible, but it's not typically the issue.
