How does one clean fuel injectors? I didn't have a good experience with fuel additives (I guess chemicals are too strong for old gaskets or something). Has anybody done it in the shop? And how much does it cost? :gulp
nothing still beats runnning a high grade octane and taking the car for a nice hard drive on the freeway. injector cleaners are a little too harsh for cars but deffinately do the trick. obviously to save money and keep your carbon deposit situation at a minimum, try doing the above mentioned method.
