Question about 1993 Ford Taurus
The code 157, MAF sensor comes on. I cleaned the sensor with MAF air flow cleaner, put new air filter in, and did a visual check on the wires and they seemed ok. I used a code reader and cleared the 157 code. The engine light came on again with the 157. By the way, the check engine light comes on at about 45 mph and stays on for a few seconds, then goes off again. I am trying to pass smog. What do I do next?
That is the code for your down stream o2 sensor . you need to replace that
