where is the IAT sensor?

this is a fuel pump issue. Its not common but I have sen it on Saturn's before.The fuel pump is not working to give proper pressure to the injection system.Most injected cars need a full 30 to 35 pounds of fuel pressure to start properly.When you first try and start it it takes it a while to build the pressure and so only small bursts of fuel enter the injection chambers. So when it does finally give you full pressure you already have some fuel in the chambers and it then tries to burn off it all at once making it like its flooded so it causes it to bog out for a little bit till all the excess fuel is burned off.
Take it to the dealer and have them test the fuel pump and fuel line pressure at start up.
They should find the problem. Good luck!

05 sat should be under warenty! Even shitty saturn dealers are supposed to diag that.. should be really easy to figure out. Dont kno much about american or jap cars but it sounds like spark plugs even with 18k miles if you had a prob with the mas air sens.. that would cause the car to posibly run rich eventually causing long cold starts. Or could be a fuel issue.. jus take it to saturn and be firm with them.
