But could my fuel pump be the reason why its idling so bad? My ECU is stock, and everything else except for the motor. Air Pump, EGR valve or any of the vacuum lines leaking/malfunctioning would be my guess. I had him check everything except for my air pump, which I will ask him about tommorow. Ideas?

Get some sort of ECU and get it tuned.

My air pump connector disconnected itself a little while ago at the strip. I previously accidentaly broke the little clip that holds it together when I pulled the engine. Anyways, after the run I thought I blew my engine because the idle was rough. That was scary!
Edit: I forgot to ask! If only the secondary ports are ported, will the engine still idle rough?

I don't think it's the rough idle Ripzta's after, but the distinctive exhaust note of a ported 13B REW 
I have a large street port job from KDR, and the motor definitely has a more aggressive exhaust note (especially with full open exhaust)...oh...my idle's nice and smooth even without an air pump (running a midpipe and RB dual tip)...BTW I have a Power FC (which compensates for the lack of airpump load on the motor).
