take off your intake and you will see 2 holes inside. when it does it, put your finger over each hole one at a time. don't let it suck your finger in. but if it's the top hole that stops it then it's the aic or whatever it's called on the back. If it's the bottom hole check your fluid level and make sure the automatic choke thingy is screwed in all the way. it's the thing on the bottom of your throttle body where coolant goes in. You can bypass it too.
