When your car is properly tuned, the engine, computer system, fuel system, ignition system, and emission system are all working together in perfect harmony. When it’s not, your vehicle is not performing with optimum power and efficiency. As part of a tune-up at SGA, we’ll check (and replace if necessary) your sparkplugs, ignition coils, distributor cap and rotor, and ignition wires. When we’re done, you’ll enjoy a better ride, and likely save money at the gas pump.
