I have a 2003 Ford Ranger with about 103K miles on it. I've noticed a drop in fuel mileage, and am preparing for a trip this summer. I'm already planning to replace the spark plugs, air and fuel filters, PCV, and run some injector cleaner through the fuel system.
My friend told me that he had his truck's air intake system serviced. He said that the mechanic sprayed something into the air intake then ran the engine with the RPMs up and black smoke came out the exhaust. Afterwards his truck ran more smoothly and with better fuel economy. It seems that I should be able to easily do this myself. However, I have been searching online and cannot find any information on how to clean the air intake system or what agent is sprayed into the system. Thanks for your help!
