Any quick solutions to these codes?
I have a 1988 Eldorado, and I'm getting the following codes:
Is there one common problem with these cars that will throw these codes? I know the B119-B122 are for the IP, but it works perfectly, all lights are functional. The B448 is for low refrigerant, which is correct, B450 is high coolant temp, which is puzzling because the car has sat for 3 days. the B552, the Keep Alive Memory, I have no clue what that means. I'm a new Cadillac owner, if anyone has an idea what could throw these codes, please let me know. The car runs rich, and I'm wondering why. I have no idea.
