Problem with car shutting off ?

[autumn 2 ashes]

Hey, guys i have a problem, lately my car is having a tendency to shut off at idle (like at a stop light or if i idle for a long time) this might sound wierd but when im at idle the car kinda of boggs and sounds like there is air passing through the engine. So far i have replaced the cap and rotor and the fuel pump and filter and it seems to be doing a little better but it sounds like it still wants to shut off. You guys have any ideas im kinda stumped ? thanks for the help!!

check all your vacuum lines and make sure there isnt any leaks. also check and clean your idle air motor. lots of things could cause that problem
