1989 Corvette Running Lean. No Codes.
Pulled multiple spark plugs. All of which are bright white, they are a few months old now. Ran a diagnostic, and it said Normal No Codes. Any ideas?

What does the O2 sensor say? How old is the sensor? I toss mine in 5 years. Hopefully not coolant but having them in all 8 might be too much of a coincidence. Check the fuel pressure and what injectors do you have? Multecs or Bosch?
