90 Volvo 240 231 fault Code
Hello All
Starting to get a SEL after a 10+ miles drive. I checked the codes and found a 231 code. Which is fuel mix to lean to rich at cruise. I have cleaned the Mass Air flow Sensor and throttle body. I have used a whole can of Brake cleaner to check for vacuum leaks. I’ve replaced the O2 sensor. Would any one out there have any suggestions for me, Thanks.
