anyone?

 

bottom hole? ummm take a picture for me... How did this hole come to be?

 

Its a vacuum leak. Once you get it fixed, your idle will return to normal.

 

it could be the iac valve, same thing was happening to my car. hth

 

i had that problem on my car changed the IAV didnt work did the same test you did by covering the hole your talking about and that test if for the FITV (i think its called). its on the bottom of the TP.

keith

 

is there any way to fix the FITV? i took it apart and screw the white piece back in and i still get the same idle problem

 

?

you probably have the port open on the bottle of your throttle body. I believe that it is the coolant bypass, there sould be a valve attachement that bolts to that that covers the vacuum port. Did you recently put on a ported throttle body?

 

no the TB is not ported and i dont see any ports open, i sprayed carb cleaner in the TB and intake manifold area and there were no signs of a vaccum leak
