sounds like what my fox body 4 cyl. did when i put a bbk intake on it. would rev up high on start up, bog down and die, wouldnt go past like 2000 rpm. ended up fixing it, i had a leak in my intake piping so i would check there, it sounds like you mite have a combination of problems tho. possible mass air flow sensor? get some isopropyl alcohol and clean ur sensor with a q tip. check you wiring to it and make sure u dont have any leaks in the intake system between MAF and TB
