warning lights
 

I have a 1998 C5 stock corvette with 26k miles. I have had many sensors replaced. Still get "Check Engine Light" coming on. It has been in and out of shop a lot over the last year. Runs perfect. Sometimes I have to pull the key after starting the motor and wait 10 seconds then start again. I have had 3 refurbished BCM's replaced in it. What is wrong?

First question, who is reading the codes and doing the work? What quality of parts are being used?
It may be time to visit the dealer or a Corvette/performance shop.
