Can anyone explain to me why a bad vacuum advance causes a single stumble under wot?   I have a black 87 TSI (161K miles) I bought new in 1987 which is now running great after I replaced the vacuum advance (2nd time in its lifetime). I've never quite understood why the vacuum advance causes the single hiccup around 3k and then continues to accelerate. Thanks

I have a set of 89 conquest tails in perfect condition, no cracks. Text me for pics 609-240-9876 200 + shipping

Anybody got a good license plate holder (and screws)for an 89'. Texas is sometimes unforgiving for not having two plates on a car. Lost a rear lift support in the paint shop. One is good and the other gave up the ghost. I'll take the set if they are good. Let me know!   Glenn

Please help me sell this car!!   http://cnj.craigslist.org/cto/3944047201.html   908-977-5822 for more info and pics. Car has rust.
