cleaned TB and idle still dips to low

[I-luv-em-all]

i blocked off the egr, so i cleaned the throttle body and the idle still dips to low when u put the clutch in. what should i check or do next?

check your idle set screw...idle something screw i cant remember the name for some reason.
i think its idle set screw, its the screw on top of the TB on the bottom left corner, if its too lose that could be your problem, leave the car running and screw it tighter and loser to see which is best.

Base Idle Speed Screw?

Also, do a intake leak test. The tb could be leaking at the gaskets. It also likes to leak at the BISS(the base idle set screw that was reffered to earlier). If so, there's an o-ring at the bottom that might need to be replaced.

f so, there's an o-ring at the bottom that might need to be replaced.

The o-ring is at the top of the BISS Screw just below the head. If you have one down in the bottom of BISS bore it's wrong and should be removed.

If you have a logger check and make sure your idle switch is activating. This cured the idle dip for me when coming to stops.
