BuzzKill Posted February 12, 2003 Report Share Posted February 12, 2003 Its a piece of cake. Should take less than 15 minutes to do: 1: Unclip the distributor pickup wire from the clip on the old vacuum advance 2: Disconnect vacuum line on the vacuum advance 3: Unscrew the 2 screws holding the vacuum advance to the distributor (they tend to fall and get lost easy - magnetic tipped screw driver recommended) 4: Unscrew and remove the distributor cap (leave spark plug wires attached) 5: Bend down the 2 triangle-shaped points securing the vacuum advance arm (wiggle the vacuum advance and you'll see where the arm hooks on) 6: Twist the vaccum advance clockwise (looking from the front of the car) and use a flat-head screw driver to get the arm off the notch. 7: Pull the vacuum advance out. To put the new one in, just follow the above steps in reverse order. I was surprised by how easy it was to do. Link to comment Share on other sites More sharing options...

AussieStarion Posted July 8, 2003 Report Share Posted July 8, 2003 So what symptoms/how will the car perform with a broken vacuum advance unit?? Link to comment Share on other sites More sharing options...
BuzzKill Posted July 11, 2003 Author Report Share Posted July 11, 2003 The most common symptom of a bad vacuum advance is a studder/miss while accelerating. Usually it's a single miss when you get on the gas, anywhere between 3500 and 5000 RPM. It can be accompanied by a small puff of black smoke out the tailpipe (unburnt fuel), but not always. In some cases, a backfire may result (the unburnt fuel igniting in the exhaust). Link to comment Share on other sites More sharing options...
j0nes0dah Posted April 30, 2004 Report Share Posted April 30, 2004 another symptom of a bad vacuum adv is that the car will not run over roughly 115 mph. i thought it was my imagination the first time it toped out, and then i realized it was constant the next time i tried. replacing the vacuum adv cured this problem easily.
