Question about 2004 GMC Envoy
The attery gauge goes down and when i turn on my heater it almost stalls out...i changed the battery becuase i was told that was faulty but it didnt change anything...ive been told it could be my serpintine belt becuae its loose
If your idle speed is less than 600 RPM, the alternator will not be charging the battery. The idle speed could be low because the throttle body needs to be cleaned. Make sure it is cleaned front and back.

Cleaning of the throttle body is in order, grime build up is preventing throttle plate from closing completely at idle.

SOURCE: JUST PUT A NEW BATTERY
Do to the loss of battery power while changing your battery, your Engine Control Unit (ECU) has reset and need to re-gather information. It is also possible that your battery does not have a solid connection causing loss of power and loss of data for your ECU.
Check your connections and wiring to your battery to make sure you have a solid connection and no frayed wiring causing unintentional grounding, and insuring any corrosion has been cleaned from the terminals of your battery and the battery terminal clamps.
turn on your vehical and ideal it for 10 to15 minutes. Do not rev the throttle/engine during this time as your ECU will be gathering info from the idling and will adjust to compensate during this idle time. Typically you should be able to drive the vehical with no issues after this time. A 30 minute freeway drive following your idle should give your ECU a full set of info and your car should run smoothly after that.
