Default Electronic throttle control.. please help

So i got my intake and custom tunes from bama today. after installing my intake with no problem i uploaded one of my custom bama tunes. after installing i started the car up and noticed a little wrench icon, and the car had went into the "limp-home" setting. im not sure if its because of a bad tune or tuner, anyone had this problem? advice? thanks

Does anyone know if there's any way to reset the sensor yourself? Or would I have to take it to a dealership and have the whole ecu reset

Are you sure you reconnected the MAF properly and that the intake connections (at both the CAI and at the TB) are tight and sealed? Those are often the culprits of CEL's and wrench icon on initial installation. And since you still have the wrench after flashing back to stock, my guess is the MAF.

When I first installed my CAI & tune, I had forgotten to plug the MAF back in and got the wrench about 100 yards from the house.

Once you resolve the problem, the car will reset and the wrench light will go off.

Did you reinstall the stock intake before loading the stock tune?

LOL...I did it myself on the CAI install on my GT...all excited about the tune and new stuff...forgot to plug in the MAF sensor...the wrench popped up...limp mode...felt freaked out and kicked in the ***** at the same time...so I feel for the guy...and what a relief to see that plug hanging off ...

Yeah, nothing like going from a paniced "AW SH*T!!!!!" to a calm "Cool... I got it."
