Running rich

[92Talon251]

I browsed the forms for anwers but can seem one that fits my car I am keeping logs on my MMCD logger and it will read my 02 voltage in the area of 2.73 to 2.93 volts to my understanding this is Hella rich correct?? But also I am not shooting out any black smoke but I do smell gas sometimes riding down the road my brother is taking classes on automoive technology and he says that running 2.73 volts is immpossable for a 02 sensor?
I have replaced the 02 sensor with a new one and I am getting the same readings Any idea's

Some one told me a Fuel pressure regulator could fix this problem another guy said it could be my coolent sensor that is going bad i am going to try the sensor see if that works if it dont I will get a F.P.R.

Are you looking at the O2-R or O2-F readings?

 

[92Talon251]

iI am looking at 02-F there is no 02-R on 1G's

MMCd gives me a reading in both places, that's why I asked.

On MMCd the one you need to look at is O2R. Don't know why its called that, but its the right value. You will see that it is always a voltage between 0.00 and 1.00
