I have a superchip on my truck and it was set to gas save mode but when I programmed the performance tune it threw a throttle actuator forced idle and throttle actuator stuck closed code tuck turns on but just idles tried clearing and set program back to stock disconnected the batterie but nothing helped . Tomorrow I'm going to clean the tb hopefully that works. I put a new tb motor on. Is it possible that I wound the spring in the motor to tight? It ran fine all day tho

 

Specs on your truck?

 

I just replaced the whole tb. I think the real problem was the tb motor .
