Adrenln- dude im sorry to hear ur having such a beat down with ur car. I'm running the same setup as you except i dont have a built block. I have a blowthru setup and its setup exactly like yours. My IAC routes the same, and the one side of the powerpipe is plugged too. The only diff is i'm running the Lightning MAF with a diablo MAFia. I dont have any probs with my idle or engine temps and i can sit at my work parking lot with it idling for 30 min at lunch with the AC full blast in 106 deg weather. I have a Saleen Hood that has two vents in it kinda like the 03/04 cobra hood. I dont know what to tell u about ur car besides def def def find a new shop. Somebody should be able to figure out that crap easily at a good shop.
