113 fault code, short term fuel mixture too weak 850 1994

My service manual says the 1-1-3 code is a problem with either a vacuum leak or the Heated O2 sensor is bad.

1) Code 1-1-3 or 2-2-1 means that engine is running lean.
This may be caused by an air leak or an Heated O2 sensor fault. Code 2-3-1
or 5-1-2 means that engine is running rich. This may be caused by high
fuel pressure, leaking injector(s), faulty MAF signal or faulty HO2S
sensor.

How old is the O2 sensor? You can get a new one at FCPGroton.com for about $100. They are expensive because it is a heated unit. If you don't hear or see a vacuum leak try replacing the O2 sensor.

Good luck.


Mike
