Here is the problem that I am having: I am getting a bad miss/hesitation at idle and low RPM's and on a cold start-up I get a 32 code. So I replaced my EGR valve and it didn't improve so I decided to check the piece that the vacuum lines run off of (EGR solenoid I am assuming) and there is no vacuum coming out of those holes. I checked it at idle, 1500 rpm, 2500 rpm, 3500 rpm and nothing there isn't any vacuum. Could this possibly be my problem? Where is the vacuum supply for this solenoid?

Another thing that is kind of weird with the 32 code is that it only comes on when I start it in the morning, or when it sits for 6 or more hours. If I go to the store and get some stuff and go restart it once I have driven it once that day it no longer gives me the 32 code and seems to run better.

Is there any way to check this solenoid to see if it the electric part works properly? Help!

The vacuum supply comes from the bottom drivers side of the throttle body. Then it runs into the soilnoid, then to the egr. There is a 1 wire sensor into the base of the egr that is wired into the computer to indicate whether the egr is flowing or not.

 

It is possibly a bad egr temp sensor causing the code 32 I have had it go bad on my vette and my Iroc they are not expensive about 10 to 15 dollars at the dealer.
