My Toyota has come up with codes involving air and fuel mixture. I have replaced MAF sensor, fuel injectors, pcv valve and hose. Upper and lower oxygen sensors, and catalytic converter pipe that runs to the manifold. The car runs good and has power. Also when driving the headlights dim once and a while and they also dim when hitting a power window button. I am at my wits end. I need help. Can you help?
