2004 trailblazer when i turn heat on truck vibrates and turns off. was told it could be a sensor but dont no where they are or which one.


Time to clean throttle body, a dirty throttle body will cause low idle and stalling. Make sure to disconnect the battery during the cleaning process, this will reset the PCM (computer) so it can relearn to the cleaned throttle body.

Battery changed on 2004 chevy trailblazer and now it stalls out and idles really rough...any solution


Sometimes the Computer [PCM] that controls the engine will loose it's memory on how you've driven it when power is removed. It should reset itself after a few miles of driving.

What does a low idle engine light mean? Should I be worried?


{: ) If the engine is idling low, it may give you future problems like stalling, poor a/c cooling, low power, and many things. Could be your throttle body needs cleaning, or plugs changed, and also the air filter. If it's some other fault anywhere, you may need a scan tool to retrieve codes that may be present.

Engine stalls


Assuming you have the correct size battery, this really shouldn't happen! I am assuming the engine is idling at fairly low RPMs, so when the AC kicks on, it kills the engine? It might be that you need to drive the car for a bit so that the engine computer can "relearn" your settings, which disappear when you change the battery. Or, when your battery died, one of your sensors might have gone with it. There is a idle sensor on most cars that raises the idle RPMs when the AC comes on.
