Smootrc you got a problem. I have an 05 and trust me. There is a spring and o-rings inside the pump. I just did the spring mod yesterday, and also installed a Quickshot 3. The bog is TOTALLY gone. But the throttle is still hard. Gonna get the replacement spring. DID the cam mod right away also. MAN did that wake the motor up. Definitly worth the time.
