tekfx19 Posted September 22, 2004 Report Share Posted September 22, 2004 Hey guys, i just cleaned my TB on my 96 and there was a good amount of crud on there. I also cleaned my EGR because I was getting a 1406. Now my idle is higher than normal, the car seems to have more umph to it but this cant be a good thing. I looked for posts regarding this issue but I couldnt figure out which applied to my car. I am also getting a service idle control system message with the High idle code 0507. Any thoughts or suggestions? Link to comment Share on other sites More sharing options...
DFBonnett Posted September 22, 2004 Report Share Posted September 22, 2004 Try disconnecting the battery for a minute or so. That should reset the computer to the default idle setting for a clean TB. FWIW YMMV DFB Link to comment Share on other sites More sharing options...
tekfx19 Posted September 23, 2004 Author Report Share Posted September 23, 2004 i did that , like 3 times... Im thinking maybe something is stuck in the tb, ill open it all up tomorrow and see if everything is kosher.... Link to comment Share on other sites More sharing options...
Ben Posted September 23, 2004 Report Share Posted September 23, 2004 What did you use to clean it? Link to comment Share on other sites More sharing options...
Scotty Posted September 23, 2004 Report Share Posted September 23, 2004 As DFB said, you must disconnect the battery and let the system do an idle learn and it will settle down Link to comment Share on other sites More sharing options...
tekfx19 Posted September 23, 2004 Author Report Share Posted September 23, 2004 Ok so now my next question would be what happens when u disconnect the battery for even like 10 minutes and the idle still stays at 1100?I used carb cleaner to get the gunk off i disconnected the tb to get to the other side easier, i double checked that there were no gaps when i put it back on, but maybe im wrong.

Logan Posted September 24, 2004 Report Share Posted September 24, 2004 Well there it is.....you took the throttle body off. The throttle body uses a large 'O' ring. After a spell these will swell up. If you dismantle the TB from the intake...its nearly impossible to get the 'O' ring to fit back into the groove. Result is a vacuum leak. Any time I have to take one off...I always have a new 'O' ring there. Its big....about 4 inches in diameter.

tekfx19 Posted September 24, 2004 Author Report Share Posted September 24, 2004 well, i remember taking off the throttle body before and i just made sure the gasket was aligned up, are you refering to the gasket or is this O ring something else, where can i get another one if this is indeed the issue?

Logan Posted September 24, 2004 Report Share Posted September 24, 2004 Thinking about it.....I think the older cars use the big o ring. I think the '96 actually uses a gasket. That being said....the service manual states.... "Important: Use a new gasket." anytime the TB is removed.
