Many customers call and ask for a “tune up” because they may have noticed that their vehicle is running rough, hesitating, or stalling or they have a noticeable loss of power or decreased gas mileage. 

However, today’s vehicles do not require the type of adjustments that used to be needed.  Gone are the days of adjusting the air/fuel mixtures on the carburetor and replacing or adjusting the points on the distributor. 

Modern vehicles have computers with electronic components that either work or don’t work and are not designed to be “adjusted”, but rather replaced when they do fail. These include oxygen sensors MAP sensors, cam/crankshaft position sensors, electronic control modules (ECM’s), and the list goes on.    Typically, when one of these components fails, or starts to fail, your vehicle’s Check Engine Light will go on, your vehicle may go into “limp mode” (it drives, but with very little power), or it will quit altogether and will require a tow to a repair shop.
