Keeping your engine well tuned will improve performance and save fuel. Performing a complete tune-up can often take care of nagging running and starting problems. It is more difficult to troubleshoot a poor running engine that is not tuned.
Thousands of "do-it-yourselfer" customers perform their own tune-ups every year and they save good money doing it.
With a factory Service Manual and the correct tools, tune-up's are snap.
The Engine Owners Manual that came with your engine has a wealth information pertaining to
tune-up and maintenance procedures and schedules.
