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!!
