Went to start my car today and it did but died right after. went to start it for the second time and she fired right up. driving down the street my car felt somewhat sluggish. i floor it in second and it isnt going anywhere. it sounds like its having trouble sucking in air but at the same time there is another noise that sounds like its leaking air somewhere.it gets really loud when i am flooring it. louder than usual but its isnt gaining any speed at all. i tried checking for a IM gasket leak. its fine. took out my CAI and put in the stock air box. and it still does this noise.

anyone have any ideas on what this could be??? car was running fine last night. everything went down hill today.
