Had to switch from the Vent thread to the Happy thread- just got my car out of the shop ($500) and it runs great! I could totally tell my car was happy. They said the only other thing they could think of that it needs is a new muffler (it still has the original, and sounds like a muscle car) but that it could wait until my wallet replenishes itself. The mechanic said that my car is really in great shape, especially for it's age, and well worth fixing as opposed to dumping for a new car.
(I really do love my car- best car I have ever owned).
