Have a tech question for everybody. I have a 1986 C4. I had new tires ordered for it so I decided to get the most out of the old ones. On the way home from work one morning I decided to stop and do a burnout on our country road. Now when I start the car instead of firing right up it cranks for about 5 to 10 seconds before starting. It use to start as soon as I hit the key. It only has 78000 miles on it but I'm lost when it come to all the injection business. Any ideas othe than stop doing burnouts.
