I cranked my truck at work and right when I gave it gas it felt like it wanted to die.... and on my instrument panel it said "Engine Failsafe Mode". I turned my truck off and sat there for a minute before cranking it again. The Engine Failsafe Mode was off. I drove home (15 miles) neither it or my engine light came on. The next morning I drove to work with no problems. I have a Edge programer on my truck and looked to see if there was a code. Sure enough there was one.... Throttle Actuator Control. Ive gotten mixed opions on what this is. Is it the throttle body? Any help will be greatly appreciated. I have a 5.4 Triton with 102k miles. New plugs a month ago.

 

Nobody has had this happen?

 

Yes. Clean your throttle body.

 

Cleaned throttle body today.... and boy was it dirty!! Got it all put back on and it runs great. Throttle response is awesome. Thanks for the help with this problem.

 

Good deal, love it when we fix a problem.

 

Most of the TAC codes are due to a dirty TB.
