Got engine codes...Need help

[SHO bulley]

I ran a running and not running KOER and KOEO self test for EEC. For not running and running i got the same codes. "91 02S not switching and SSI CKT Fault." Also, 25 no knock signal. I guess i need new 02 sensors, but whats up with the CKT fault, is it a circuit? Can someone help me out?

The 91 is "System running lean - Fuel control" OR "Transmission SS 1 circuit/solenoid problem - Transmissions", but not both.

You probably have a lean mixture. The cause would be the question.

The 25 means that there just wasn't knock detected. That may very well have been because there wasn't any knock to detect. Not to worry.
