Take it out on the road, give it the gas and wow...she really moves, let off the gas, the BAS/ESP light comes on and I get no throttle response, stop the car turn off the engine, restart and take off, runs great until I let off the gas, then the light comes on again and again no throttle response. Did a couple of throttle resets as well as disconnect the battery with no change. I'm thinking perhaps air leak somewhere or ECU learning process. Anybody care to hypothesize on this?
These are the codes from my Torque Pro.


Not to sure they are 'normal symptoms' as I did that mod and the car never even coughed.

As others have said you may have a bum throttle body. Especially with those codes.

Did you reinstall the old MAF sensor?
Did you use a new O-ring and make sure there are no air leaks into the system?
Is your battery a good one and not ten years old?
The answer to all these questions should be yes.
