engine check codes 26,27 and 77 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

the fan one. have you checked your fues? OBD 1 is so hard because it could just be something relative to those codes not exactly what the code is saying.

The fan fuses keep on blowing I have looked at the circuit but I could not find any wiring problems. I was thinking about installing a fan switch, if anyone has had this problem I would like to hear how you fixed it. What do you think about installing the manual switch?
