I upgraded my throttle body recently, during idling the ETC light comes on and the engine goes into limp mode. I have tried disconnecting the battery for 15+ minutes and the ETC reset. Each time the ETC continues to come on. The code come son during idling, I have reset the ETC and driven the truck for 30-40 minutes and the code never came on until I came to a stop and the engine was at idling speed again.

Is there something I am doing wrong?
Something else I need to upgrade?

Currently I have removed the upgraded TB and put the stock back on. I have also added a CAI and TB spacer.

 

What is the code?
