Try this intake

while the 10 sec. it is running take some either spray and spray along the ports of the intake this where the intake meet the heads. spray along there and if the engine speeds up or continues to run the intake gasket has a leak. also on throttle body injection if the air cleaner is not on the air/fuel mixture will become to lean to run after the engine fan blow the fuel away from the bowl. I hope this will help let me know if it does. ************* on here at jessedenny47
