well i was working yesterday and today and i found that one of my intake gasket wasnt sealing so i took the intake manifold check all the gasket, put more gasket sealant and put it back torque it down the bolt and nd put every thing else and i start it back. it do the same thing but sound more happier but it still quits after 15-30 sec. what could it be? i think is fuel problem but i still dont know. i have 15 inHg of vacuum on my boost gauge when it start and idle. it that good or not? my set up is on the sig. thanks

 

another thing does the air temp sensor will cause this problem? because im using a Turbo II oneand it look diferent
