So I started my car today with my new a/f gauge. I didnt drive it though since it was leaking some major oil and I just droped the engine....I just started it and let it idle...

Is the gauge supposed to read all the way rich during idle ??
and even when your pushing on the gas when your in neutral ??


Whats the reading supposed to be in neutral ? or do I have to wait till the sensor gets warm or something ?
