When your car or truck is properly tuned, the computer system, fuel system, ignition system, and emission system are all working together in perfect harmony. When they are not, your vehicle needs a tune-up. As part of a tune-up with Newman's Automotive, we'll check (and replace if necessary) your spark plugs, ignition coils, distributor cap and rotor, and ignition wires. When we're done, you'll enjoy better vehicle performance, and likely save money at the gas pump.
