I just finished putting a 5.3 into my crawler. I did the wiring harness and all the other stuff that comes along with it. After working out a few problems I got the motor to start. Once it started it went full throttle. And know that's what it does every time I start it. I've checked the intake for air leaks and can't find any. I have changed the throttle body and sensors. It is a different intake then came on the motor. Just looking for ideas on what is going on.

Is it throwing any codes? Possibly a U0107?
I'm running into basically the opposite issue, no throttle response after blipping the gas a couple of times.

Just ordered a obd2 port last night to be able to check.
