I have codes now

I have a question. My 2006 F-150 super crew 5.4 has a issue. I can be driving down the road and then the truck goes to idle and no control with the gas peddel. I get a engine light as well as a wrench. If I shut the truck all the way off I can restart it sometimes one try sometimes more. Not good in traffic. this has happend 20-30 times and I have changed the TPS with no change. Anyone know what to do???

2 of the codes I got are

P2104- TAC system forced idle
P2112- TAC system stuck closed

Changing the TPS did not seem to fix this issue could it be the ECM?

Repair or replace the throttle body.
You write; "2 of the codes I got are"; Did you get any other codes?

No I only had 2 codes but the check engine light did not stay on this time. How do you fix a throttle body? There is not much to them on the ford.

Most likely not the PCM if there are not other codes. Like shorebird said...replace the TB.

Ok it happend again this time I got one extra code then before and code P2104 showed up twice but the truck only dropped to idle once.


3 of the codes I got are

P2104- TAC system forced idle (2 times)
P2111- TAC system stuck open
P2112- TAC system stuck closed

Will this extra code help with finding out whats wrong?

It is of no extra help than before it showed.
The TAC ( throttle actuator control, IE; throttle body ) is malfunctioning.
Get it fixed ( cleaned ) or
Replace the throttle body.
You have the solution in front of you.

Shorebird should I clean it with carb cleaner or is there something better? I will try and clean it before I buy a new one. Do you have an idea if I need to buy a new one where would be a good place?
