i have a nissan240sx with a sr20det redtop and im able to start the car but it wont idle without cutting out you have to keep pushing down the trrottle to keep it alive so any sugestions are appreciated thanks

 

boost leak, vaccum leak?

 

that or idle valve is to closed.

 

its a leak somewhere. make sure all intercooler pipes are hooked up and all holes in the rubber inlet neck for the turbo are plugged up. also, make sure you still have your throttle stop screw in your throttle body. this holds the wheel in a certian position when your foots off the gas.

 

thanks for the help
