I'm not saying the 02 sensor is bad, I, m talking about fuel trims. The fuel trim reacts to what the 02 sensor is doing. If you have a digital multimeter you can look at the 02 sensor signal to see if exhaust is rich or lean.
If your fully obd1 compliant, you check your own troublecodes? Without being able to do some tests, it is hard to track anything down.
