Older cars need a tune up every year or every 16 to 20 thousand kilometers. New vehicles with electronic ignitions and equipped with fuel injection need a tune up after about 25 thousand km and some can go 100 thousand km without needing one.
Specific Signs You May Need a Tune up
- Your vehicle stalls often for no reason - worn spark plugs may be the culprit. They can be worn, or the gap between spark plug electrodes has altered and needs adjusting, sometimes electronic sensing devices are in need of adjusting.
- We all know the feeling of an engine that is running roughly, especially when accelerating, or even at idle. A tune up is likely needed at that point.
- When your car becomes harder to start, the problem can be the battery, or other parts of the staring system and that should be checked, but other components can be the cause such as the fuel injection system, or in the ignition system which includes spark plugs, or in general it can be faulty electronic components such as the electronic control unit (ECU). 9 Reasons You May Need a Car Tune Up
If you cannot pinpoint why your car may stalling, take note of the conditions such as outside temperature, your use of air conditioning and any recent garage visits you may have had. The leading benefits of having a tune up are: immediate improved gas mileage; enjoyable smooth performance; longer engine life.
