Ok. You hadn't said if you'd checked the AFM or not. You have. Try holding it slightly open with a finger (gently) and see if you stay running. May need some help with that, unless you have stretchy arms. No intake leaks? Is the intake tube connected to AFM? Not to insult, but I've done it myself. Immediately following engine install, got excited, then there was about 1 minute of looking around, tube on, good to go! So...just a thought.
