Pulling this code. Need help. PO170 Fuel Trim Bank 1

[BacknBlack92ESi]

I had some problems with my car latly. I won't go too indepth if it is actualy needed.

I used a friends Code Tester here at work. Pulled this code.

PO170: Fuel Trim Bank 1.

Does anyone know any info on this? I know it is a Lean Code. But what is actully causing me to run lean? Today I am going to log some runs and see when and where I start to lean out at and that might help pinpoint the problem.

Any info will be great.

Thanks

Brandon

Check your O2 sensor. Thats why mine was throwing that code.

Which o2? The first one or the secondary one? I am guessing it would be the first one in the o2 housing. The one after where my cat "should" be wouldn't trigger that certain code should it?

It'll be your front. If you got a logger check to see what kind of voltage you are getting. I had 0.
