so I am finishing up my swap and today I started it up and it will run good for about 2 seconds and then its like it goes completely lean and rough idles at like 300 rpm. The throttle response is great though, it runs really good as long as you press the gas. has anyone had these same experiences? and if so what did you do to fix it?

check it for codes in the diagnostic mode.

Chances are you have a vac leak or a problem with your AFM.
