Loss of RPM under breaking
This ONLY happens when I am under breaking and coming to a stop. It never happens on its own during idle.
The RPM's will drop to around 500 or LESS when I am almost stopped and then when the breaking action has finished, RPM's go back to normal ( or until I give it some gas)
What's the deal with that? It's so weird. Any ideas?

Clean the Intake Manifold EGR Passageway and the EGR valve itself.
Common problem on 99-00s. It's not difficult, just make sure to keep track of all your bolts, and I like to use some tape to note all of the vacuum lines I remove to mount them back up. Lastly, on steps 17 and 18 of the IM cleaning, no need to use Q-tips, just use a boatload of Throttle Body cleaner. I've heard some people using more than a full can just to clean the thing.
