Yesterday on the way home from work my car started accelerating poorly, and this morning it was hard to beep running....when i popped the hood, i manually accelerated it through the linkage and it revved fine, but when i hit the pedal, theres almost no tension and it only revs lightly unless i hold it down. theres a piece of metal behind the oil filter that has one spring attached to it (its in the shape of a V and has multiple holes in it). Did i break a spring or something? cause its obviously somewhere between the pedal and the linkage there....i need help cause im a courier and need my car to run by monday morning!
