Hi, have a 1999 Toyota Camry 4 cylinder. California car. Codes are P0171 (Too Lean) and P1133 (Fuel/Air Meter Control).
The engine light is intermittent, meaning it will go on for a day then stay off for a couple weeks. At first it seemed innocuous. But I want to get this fixed.
I read it might be an O2 sensor. Is this easy to replace? In my youth I used to repair/rebuild American muscle cars, so I know my way around cars. But if this is a major job that will take several hours, I'd rather let the pros do it.
Thanks, Matt
