I just noticed this happening recently,

but when I'm driving and coming to a complete stop, (with my foot off the gas) my engine is still revving at around 2000 RPM UNTIL I come to a complete stop, then it drops to 750-1000. It go back to 750-1000 a couple seconds AFTER I've made a complete stop.

I thought it was the edge of my foot still hitting the gas because I just put new pedals on, but I looked at it closely and thats not it. What would cause my engine to keep the revs high?

Also on another note, I don't know if this is common, but just recently after I would start up my car in the morning and started driving, couple minutes later, my emergency break light would light up and to remedy this, I would tap the break pedal and it would go away, e-brake handle, vice versa thinking it was stuck?? Are my break going out too??

Car is an 00' 28,000 miles.
