well let me start.okay u know the square looking thing in the front of the passenger side vavle cover that the water lines run thourgh it for the heater?okay i removed it baecause i live in florida and i dont nedd it but there was this lil plastic hose that gos connected to it and runs to the a/c box im guessing its a vacum.okay wheni turn my a.c on and im at a red light my car idles bad but not horrible u feel the vibration.so im guessing it has to do something with that hose.when i turn the a/c on it sucks in so what or were can i connect this to get rid of my problem

 

i would just plug it, i would guess by the bad idle that it is the line coming from the vacume source, not a line that needs a vacume source.

 

okay if i plug it or leave it open it stilll idles bad at a light.what cloud it be?

 

put your finger over the end of it, does it suck? if it is sucking, you need it plugged.

 

yeah it sucks y?but i have it pluged and my idle is still bad what else can it be

 

bad idle can be alot of things. from vacume leaks, to a fouled spark plug, to dirty injectors.

 

welll my spark plug are new and my fule injectors make a perfect cone,so its probally a vacumn leak okay can it be those egr looking things under the dash that run to the a/c controls becaus one hose is badly leaked
