If it is plugged or dirty gas will have a hard time getting to your engine......also, go to autozone and have them put a meter on your alternator and see how strong it is.....a weak alternator will sometime start and usually cause your car to die and stall........driveway mechanic*********|||EAsy I have been seeing these question alot lately it's simpe you may have a vaccum leak see if you hear a hissing sound like sucking second it could be your idle control sensor easy 40 buck two bolt job|||possibly you may need a tune up change the spark plugs and spark plug wires ...somthing cud be busted u shud just get it checked out ..
