My Lexus ES200 also had the fuel injector warning light come on a while back, and the solution was surprisingly simple. The first step in injector maintenance is cleaning: I bought a bottle of fuel system cleaner from the supermarket, added it to the fuel tank, and drove a few hundred kilometers on the highway – most of the carbon deposits were cleared out. Afterwards, to turn off the warning light, I connected my phone to the car's OBD port via an app, selected the maintenance reset option, and the warning light went off instantly. The whole process cost less than thirty bucks and saved me a trip to the dealership. Now the car accelerates smoothly, and the engine feels brand new. I recommend using the cleaner every 10,000 kilometers to prevent clogging – this method works especially well for older cars.
