Throttle body has nothing to do with the gasoline, it only regulates incoming air. In order to find the gas leak you will need to remove the air resonator assembly that goes from the air filter to the throttle body. Then you can get a look at the fuel rail and injector hook-ups.

SOURCE: battery removal on a 2004 GMC Envoy

The battery is on the right side behind the fuse box. You need a metric set to undo the 3 screws. Theres one that attaches to the body, one to the bar that goes along the top, and theres one on the left side below the vacuum hose and air induction. After you've taken out those three, you should lift the whole thing out(battery and shroud) together. It's hard to take the shroud off before you lift the battery out. After that, you have to pry the shoud off the battery. The two terminals in the back make it hard. Then just go to any auto parts store and they'll give you a new one.

Yes under your hood on the passenger side, take off the plastic fuse holder lid and it will tell you on the backside which fuse is for the taillights.

You may have two problems, a dirty throttle body and low AC refrigerant.

The throttle body needs to be cleaned, grime in this area prevents the throttle plate from closing completely and allowing air to enter, making the air/fuel mixture lean. Make sure to clean the front and back sides of the throttle body. Also, disconnect the battery during the cleaning process to allow the computer to reset and relearn to the cleaned throttle body.

The HVAC system needs to be checked by a HVAC technician. Just charging the system would be a temporary fix since there maybe a leak.

Hello: Get some carburetor cleaner, remove rubber tube going to the throttle body. Spray cleaner on rag and open throttle plate and clean all black stuff (carbon) off the throttle plate and the inner bore of the throttle plate. Make sure its clean, You can spray some in the throttle body but not very much as too much and you cab blow the engine up. If build up is bad (carbon) go to Auto Zone and purchase a small brass bristle brush to help remove carbon.

I replaced my battery in my 2004 GMC Envoy last week now the car cuts off/stalls whenever I come to a complete stop. It fires right back up once I put it back in park and start it again.


The throttle body needs to be cleaned, When you disconnected the battery, the computer reset to factory defaults and now with a dirty throttle body, it will run poorly at idle. Make sure both the front side and rear side of the throttle body are cleaned thoroughly.
