1999 Triton 5.4 Around 115000 Miles. It Is Running Sluggish And Has Been Shifting Funny. When I Stomp On It It Will Shift Up And Only Hit The Passing Gear If It Is Floored. I Took It To Autozone To Read The Code Because The Check Engine Light Has Been On And It Was Reading The Egr Valve. Replaced It And Nothing Changed Reset Light And Came Back On And Read The Same Thing? Any Suggestions?
