thornhill Tune up & Fuel System Service

Dirt, varnish build-up, corrosion and carbon deposits restrict the flow of air and fuel to your engine. This happens with all fuel-injected vehicles.

Deposits in the fuel and air intake system that cause:

  • Hard starting.
  • Stalling.
  • Rough idling.
  • Hesitation.
  • Knocking.
  • Loss of power.
  • Poor fuel economy.
  • Increased emissions.

If it has been a year or 25,000 kms your engine could have already built up deposits.

Completely clean the entire fuel system of deposits.

  • Fuel lines
  • Fuel injectors
  • Intake valves
  • Combustion chambers
  • Throttle plate and throttle valve

Restore the fuel system to its original design for:

  • Easy starting.
  • Smooth idling.
  • Increased power.
  • Eliminate knocking.
  • Maximum fuel economy.
  • Minimum emissions

Routine fuel system maintenance helps avoid expensive repairs.

Spark plugs light the fire in your engine's cylinders, firing about 25 times per second during normal driving. If even one of these sparks is missed (called a misfire), you'll feel it as a momentary stumble in the engine's performance. While there are many causes of misfire, worn or dirty spark plugs are a common culprit. Additionally, worn spark plugs will cause your vehicle to run less efficiently, which means decreased fuel economy and power. It is generally a good idea to replace conventional spark plugs every 50,000 Kms. Platinum or iridium spark plugs can last as long as 96,000 or even 160,000 kms. But again, more frequent replacement will ensure your engine is running its best. We are the experts in Thornhill tune up.
