My check engine light came on..I have the code

[HerkEngineer]

Hello everyone.

I just jumped E1 to Te1 and got the codes
25 and 26

25 Air/Fuel ratio lean.
26 Air/Fuel ratio rich.



O2 sensor output in less than 0.45 volts for at least 90 seconds when O2 sensor is warmed and 1500 rpm or above.

What do I need to do now? Is my engine in trouble??
Any suggestions would be appreciated..thanks in advance.

It sounds like you have a shot injector. Start the engine and listen to the injectors.....you should hear a slight "tick" Most bad injectors will fire too rapidly therefore causing the fuel mixture to be too rich. I'd pull the injectors and clean them with some carb cleaner or other highly combustible fluid.

Well, I popped in a bottle of the B-12? fuel injector cleaner and well..no more light and she runs like a champ..

thanks for the help
