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 Link to comment Share on other sites More sharing options...
GOOB Posted May 13, 2004 Author Report Share Posted May 13, 2004 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?

jgr7 Posted May 13, 2004 Report Share Posted May 13, 2004 Goob it is very easy to clean the TB. Do a search "throttle body" and you will be able to read what you need to know. Jeff Link to comment Share on other sites More sharing options...

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.
