Newbie needs help CEL error 25

[ezgrand]

Hello to All!

I recently bought a 1992 FJ80 with the 3FE motor. It runs ok,
a tad underpowered for mountain climbing. I bought it with the CEL on and the former owner never dealt with the problem

I've checked the forum and very few references for CEL error 25.
I think it is lean mixture.

I am thinking of o2 sensor as the problem. What are the chances that the 02 sensor would throw this code?

Any other causes before blowing away $100+
Thanks!

Replacing the O2 sensors would not be throwing away money. They should be replaced every 80-100k anyway. Performance can and will suffer when they're left much longer than that.

Code 25 is air-fuel ratio lean.
