when leaving work today, i noticed my rpms where up around 2000 at idle. before i put it in drive, i tapped the gas and they dropped back down to normal (around 900-1000)

........throttle body cleaning?

I have the same problem and have been told that the thottle blade is being held open by carbon. I am about to clean mine also. I do the same thing, put the car in neutral and quickly pin it and release it and it usually clears.

I see you are from Virginia Beach i love it there and have stayed at the Cavalier Hotel. The street performers are terrific, and I miss Mahi Ma's!! Mike

Early on sailors navigated by the stars at night and the North star became the symbol for finding ones way home. Once you know where the Northstar is you can point your ship in the right direction to get home. So the star became a symbol for finding ones way home or more symbolically even finding ones path in life.

just moved here at the end of last summer...military. i have been going full speed between work and home and haven't had too much time to relax and enjoy the area. although i have visited in the past, this will be my first full summer here.

back to the throttle body...is this something that we could clear up with a little WOT action? I have not touched this NS engine yet ("scared") but I was pretty familiar with the 4.9 in my old 91 Seville. is there much of a drastic difference?

The idle speed control motor could be acting up. There is a LOT of information in the archives on testing the closed throttle switch and idle speed control motor.
