I recently bought my first Audi which is a 1990 Model 80. The person I bought it from said that it would quit on him periodic. I had it quit on me once and I cleaned the ground which was quite corroded. It ran good after that for about 300 miles and then it quit on me again. I have replaced the distributor since I was not getting any fire from the coil, but that didn't do it. I still have no fire. Any suggestions would be greatly appreciated. I'm thinking it might be the computer, but would appreciate any other suggestions before I buy one. So far I love the car (If it would run)
