Ok Testarossa guy's - Beautiful clear summer day here yesterday just west of Boston, not real hot or humid...just perfect, so me and my daughter took our 91 Teastarossa for about an hour long ride. Much of the ride was through the country backroads of Sudbury, Concord Acton and out on to Rt 495 for the short 10 mile run down the highway back home. The first half of the ride was a very leisurely 40-50 miles an hour at best and then a run down 495, at 75 - 85 miles an hour...nothing crazy with my kid in the car. The car ran great! However, after about 5 minutes, and lets say it was 80 miles and hour, the Slow Down warning light came on for Cyl 1-6. The warning light came on twice in a row for about 3-4 seconds, went out and never came back on??? The car has about 2,400 miles on it, and just had a 30,000 mile major in May this year. Thought?
