car tossed me a cel Sunday, took it in, got fault codes P0301, P0302, and P0303
They replaced some cooling sytem stuff but were unable to tell me what happened and why. Anyone know so if I infleunced these codes I can stop what I am doing wrong. They also state to use 91 octane only, which I always do, and let the car idle for a minute before shutting down.
Thanks in advance for your help.
