My 79 low mileage vette began to stumble badly recently. I only use Chevron techron gasoline. I decided to take it to WestCoastCorvettes in Anaheim. Going uphill on the 210 frwy the vette fluttered so bad I had to pull off, and have the vette towed. The engine was bucking like a mule. Cost me $165.00. I have never raced this car. Can any of the viewers respond by letting me know if they had had a similar issue, and how was it fixed.
