Hi,
The only thing I have available is for the evaporative emissions system (EVAP). Take a look at the two pics below. Let me know if that is what you need or if there is something specific you are looking for.
Take care,
Joe
See pics below.

On second thought maybe this will help. Sometimes when idling the RPMs will dip really low or even occasionally stall, and sometimes it picks back up. I also have delayed take off but that doesn't happen much.

Have you ever checked the idle air control valve (IAC)? The IAC is what is responsible for maintaining engine idle speed. Since the idle speed changes, I would remove and inspect it for carbon as well as in the intake manifold. If there is an air obstruction, it will cause issues.
If you look at pic 1, it shows the IAC. Here is a link that explains how to service one.
