If it’s recent suspect bad gas, Heat or alcohol put in the gas will help determine if it’s just gas. I used to live in a place where I needed 2-3 quarts of pure alcohol just to keep the motor from knocking . I’d try a few bottles of Heat to start. Or if your low on gas try a different brand of high octane and add alcohol. I don’t know what your codes are.
