Question about 2003 Toyota Corolla
Lean bank one,( code scan readout) is what i'm getting when my check engine light comes on, this has happened twice so far in the past three or so months, and this time the check engine light is staying on. engine feels like it is misfiring at times, when car is idle and warmed up. what might be the problem?
I would try replacing the spark plugs. The lean code can be caused by an ignition miss as the oxygen isn't used up completely in a misfiring cylinder.
