it just started today. i recharged the ac at school today. got home then later on, i ran to get some grub. on the way home i noticed the car was idling a bit high. got to a red light, put it in nuetral and the idle went up to about 2500 rpm. got it home and popped the hood. now at idle (which is rather high) there is a loud humming sound, and if you touch the air intake tube you can feel a vibration. when i turn off the ignition the rpm gauge rapidly drops to zero and a couple of seconds the car shuts off after making a loud honking like sound. the car runs fine while i am driving down the road, except for the fact i can run down the road at about 30 mph and not even have my foot on the gas. i use this car as a daily driver and it only has 68,000 miles on it. help needed as soon as possible.
