....deeper engine analysis?
I'm considering having my Volvo smog checked just to see what's going on with an external diagnosis of burn quality.
I wonder if anyone offers a technique such as removing an O2 sensor and plugging into the exhaust stream pre-cat? Yeah, having the sensor out of the stream may cause the car to run wrong,....any ideas?
