The check engine light came on yesterday. Plugged in the code reader and it
gave me "1128". Can anyone advise what is commonly replaced to correct this
problem?

Thanks,

Ken

 

Also.....72K miles.

This is what the Bentley manual has for my '03:

P1128
17536
Bank1, mixture adaption (mult.) system too lean
- Check exhaust system for proper seal
- Check pressure regulation valve of crankshaft housing ventilation
- Test Oxygen Sensor (O2S) before Three Way Catalytic Converter (TWC)
- Test Oxygen Sensor (O2S) after Three Way Catalytic Converter (TWC)
- Check fuel injectors

Thanks, Art. I'm thinking O2 sensor. Probably bite the bullet and go for the upstream one unless someone can advise me otherwise.
