Throttle position sensor problems

I have a 2005 f-150 street boss with 79000 mile, and it is shooting off going down the road, and the check engine light is flashing. The first time I started it back up and it would idle fine, but the throttle wouldn't do any thing. After setting about 15 min. I started it up and it ran good. I checked the codes and it had a p2104 Throttle acturator control system forced idle. It happened again with my wife. This time when I checked the codes it had the p2104 and a p2112 throttle actuator control system stuck closed code. Does any one have an idea what could be the problem, or a troubleshooting guide I could use to try and diagnose it. Thanks

Usually the throttle body causes this problem about 95% of the time.

2006 f250 5.4 throttle body

Does anyone sell a decent aftermarket throttle body for a 2006 5.4 f250 that is less $$ than Ford? Thanks Lee

Try cleaning it first they usually stick because their dirty with carbon.

I had the same problem with my f250. Take the throttle body off give it a good cleaning and a new gasket and you're good to go. Maybe took me an hour to complete.
