i am using 98 model all time 4 wheel drive. when i did computerized checup for my car, the fault came of burning too much fuel. The garage man said to adust the fuel injector to stop xtra fuel burning. My friend suggested to put fuel injector medicine which clears the injectors for upgrading the performance.
Any suggestions please on this.

thanks,
qatar

It's time to look for a new "garage man" There are a number of things that can cause your car to run rich. Although it's possible to have an injector dump too much fuel, a faulty injector usually causes a lean condition.

more than likely a sensor is telling your computer to dump more fuel. Possibly an O2 sensor.
