Yesterday i go to crank up my car, and when i turned the key into the on position, it sounded like a small man with a hammer was trapped under my hoods. Then the engine turned over about 8 times before it finally caught. Once running at idle, i noticed that the throttle was basically non-existing. i tried replacing relays, reseting the computer, and pulling out my hair. this morning i tried again after leaving the battery unhooked all night, and now it wont even crank. any suggestions?
