Default Rough idle and low RPMs at startup when cold...

Hey guys, I'm a supra noobie but I've always loved the MKIII, just bought a 1990 supra turbo with a rebuild. HKS MHG, ARP head bolts etc. It's very, very clean. I'm having a problem with rough idle and low RPMs at start up. The check engine light is on and is providing me with error code 26. Something about Air-fuel rich malfunction. I took it to my mechanic and they suggested it be the MAF meter, but it was just replaced so I have doubts. I think it may be the cold start fuel injector because the low RPM and roughness of idle only occurs when the motor has been off for a while. I'd appreciate any input I could get.

Here are some pics...

I hope I didn't break any forum rules! Thanks guys.
