Hi. I replaced the Throttle body to my 2000 trans am 5.7, for an aftermarket modified one, and now it is spending 1 1/2 more gas. Is that normal?

Asked by Jun 11, 2016 at 12:23 AM about the 2000 Pontiac Firebird Trans Am

Question type: Car Customization

The car should be stronger and faster, too. I think something is wrong. It is
only 50 k miles on it.

No, the throttle body is only for air flow, I would get it live data scanned to see what systems might be out of specs.

You must realize the computer in the car controls the air/fuel mixture going into the cylinders. Throttle body, and the fuel delivery system must match the parameters of the OBDII computer. Mods like this may require a reprogramming of the OBDII depending on what you are looking for in the engines performance.

Total DISASTER... when someone doesn't know a thing about engines controls or tuning.
