I not only have the answer, but it's on the house! Just give me a vote so I can see if thier counter works! I have answered a lot of questions for free. Tried to join as a moderator and have heard nothing from anyone. Back to you problem, You have a vacuum cannister mounted on the firewall, or near it with 1 vacuum line going to it, this is a reserve tank so when you accelerate the vacuum is supplied to the A/C system. If it develops even a pinhole it will not hold vacuum! Change this tank and all should be well! The old steel coffee can types are the worst of em!
