RE: fuel problems need help
If you want to know if the system is running lean....ask the computer to check, run the KOEO/KOER self-tests combo and it will allow you to verify what the system is/has been working with. If codes 41/91 don't show up.....it's adjusting A/F according to the stoich targets the system has programmed and the feedback it receives from the O2's.
