Running Rich ?

[ryana83]

Well I think I am running rich because there is a little cloud of smoke that comes out of the exhaust. It is not oil or antifreeze because it smells like gas. What could cause this ? Bad gas or something like this. It just happened within the last 2 days. I already cleaned the MAF and also cleaned the IAB. Any suggestions?

If your engine were really running rich, there would be a CHECK ENGINE light and the 42 or 92 codes that indicated an O2 sensor was detecting a rich condition.
