This could be a lot of things. one of the tests that you need to run is shift it into nuetral when you are stopping and see if it still drops RPM and wants to stall. This will eliminate or conclude that it is a transmission issue. If it is still doing this then it could be a vacuum leak or fuel delivery issue.

Sorry, but that is a wide open question for which there is no single answer. There are a lot of things that can cause what you are describing. It could be anything from needing a simple tune up to major engine problems or even a clogged-up exhaust.

It sounds like you need a complete tune up and filter change on the car/truck. By doing this it should correct your problem. Hope this will help you.

check your throttle position sensor

had this problem on my neighbors 98 chevy truck with the same engine !!
it turnd out too be the fuel pressure regulator,you have too pull the upper intake too replace it!!

Go to Advance or Auto Zone and have them run an obd scan on it and it will pin point why your light is on and could solve your problem. This is often done for free.

low idle speed...or the need of a tune-up
