To Rich 02 sensor
My car will not start because it is to rich which I think is the 02 sensor. How do I make it run leaner for the time being so I can warm up my car to replace the 02 sensor?

The O2 sensor isn't used at startup. It doesn't switch to closed loop until it's hot. If you're really rich you may have a leaking injector.

I got it to run, replaced coolant temperature sensor, and oxygen sensor. I am not getting check engine light, I think it runs a little bit leaner. The next thing to do is timing I believe.
