I am running a Gep prizm '95 with 1.6 L fuel injected. I am wondering if cleaning the throttle body really helps mileage as it is only air flowing through? I am not talking about the TB being so dirty that the throttle sticks or anything like that. Just removing the layer of carbon about every 30,000 miles. Obviously FI cleaner through the tank does not get this carbon out as it goes a different route.
