My 95 Firebird 5.7L engine check light has come on and I have retrieved the codes and they are listed below:

26 – Evaporative Emission canister purge solenoid value circuit
27- EGR – vacuum control signal solenoid valve circuit
77- Cooling fan #1

I have replaced the ERG solenoid.

Dose anyone know what I should replace based on these codes?

Thanks
Bob
