- Adjust idle air speed
Engine
- Check tappets or lifter noise
- Inspect emission control system
- Inspect operation of EGR and exhaust
- Inspect PCV valve system
- Check air intake and ducting
- Air filter is checked and replaced if required
Ignition System
- Replace spark plugs
- Check and test HT leads, condition and Ohm resistance
- Check and test oil packs
- Check wiring etc to coils
- Check and clean distributor and test distributor cap (if applicable)
- Check battery charging system
- Check Earths
- Adjust and set ignition timing to manufacturers specification
Electronic Injection System
- Check all vacuum hoses
- Check all fuel hoses secure with no leaks

- Inspect throttle body for binding and set correctly
- Inspect induction system for air leaks and security
- Check operation of injectors and fuel rail
- Clean and check air flow meter (if applicable)

Engine tuning questions, answered
Common questions about engine tune-ups at our Frankton, Hamilton workshop.
What does an engine tune-up do?
A tune-up makes your engine run smoother, more reliably and more economically. We replace the spark plugs, test the ignition system, check the fuel injection and air intake, set the ignition timing and idle to the manufacturer’s specification, and road test the car.
What is checked during a tune-up?
- Engine: tappet noise, emission control system, EGR and exhaust, PCV valve, air intake and air filter.
- Ignition: new spark plugs, HT leads and coil packs tested, battery charging and earths checked, ignition timing set.
- Fuel injection: vacuum and fuel hoses, throttle body cleaned and set, induction system checked for air leaks, injectors and fuel rail checked, air flow meter cleaned where fitted.
- Road test: engine performance, plus a general check of brakes and suspension.
The exact list can vary by make and model.
How do I know my car needs a tune-up?
Common signs are rough idling, misfiring, hesitation when you accelerate, harder starting, higher fuel use, or the engine warning light coming on.
Are there any extra costs?
Replacing the air filter or cleaning the injectors costs extra. We let you know before we do either.
