1998 A4 sticky pedal and Throttle Body issue
 

I took my TB off the intake this past weekend to give it a good cleaning. However, the pedal still sticks at the top. Anything else that could cause the sticky pedal?
The TB has a valve actuator that seems like its been having issues lately. I'll be cruising down the road and get a sudden jerk (like when you take your foot off the gas in a manual car and it jerks). Can the actuator be malfunctioning? The car also bogs at idle and when this happens acceleration suffers. These problems tend to come and go. Meaning, I'll drive the car to work (for example) and it'll be fine, but when I drive home it malfunctions.
