Hi there, I have been chasing poor fuel mileage for a while in my ty. the other day, I found that the egr valve leaks off vacuum. 20" goes away in about 5 to 10 seconds. Is the valve definately bad? it does move when i hold the throttle up in park, but not very far. Any help would be appreciated. The truck runs great, just sucks gas even when I drive like a grandma.
