info on air fuel lean

[mustracetsi]

Hi guys. This may be stupid but need answers to it. Just bought talon tsi about a month ago. Air fuel gauge aways reads rich. One day I was raining, firs time with Car in rain. Was going. One hour drive back home. About ten mins
to my destination car went lean. Then block away from home went back to rich never happened again. Yesterday. Started raining drove the car around and notice it the air fuel moving again but stood on the rich side. Forgot to mentioned. First time was highway when went lean second city blocks. But only on rainy days. Why does this happen and any tips to prevent it.

It is almost impossible to understand what you typed. Is this a wideband o2 setup, or just a narrow band gauge with the lights?

Guess narrow band with the lights. Came with it when I bought the car

The narrow band isn't really a good gauge to rely on. I would get a wideband.

Ignore that thing, it will never be accurate. That is all they do is bounce around.

Thanks for the tips. It never bounced only in rain. But will get wide band light you digested.
