Spout Only Adds 2 Degrees Of Timing At Idle...any Ideas?

Hey everyone, I'm still hunting down some idle issues. The car runs and drives good but I have noticed that it will surge a little with the A/C on and cold starts surge as well. I have my timing set at 14*.When I plug the spout the timing only goes up to 16* or so.

Also, I noticed that there is no change in idle when I disconnect the IAC even with the A/C on. The IAC is a brand new Motorcraft one.

I checked a friends car and his idle goes up by about 10* when disconnecting and reconnecting the spout.

Any Ideas?

And I have no codes either.

Thanks in advance.

Well, I have the emission codes because I don't have any emission equipment. I did a cylinder balance test today and it passed.

I did clean the mass air and the idle seems to be a bit smoother at idle. I have a TFS Stage 1 cam with 1.7 RRs so I have the idle at about 900. If I go any lower it will surge when I turn on the A/C.

Still...I disconnect the IAC and my RPMs only drop by about 50. I'm verifying it with a timing light that has an RPM readout.

I also replaced the injector harness since I have a spare and no change either. I have 2 computers, a A9L and A9P and no difference between one or the other.
