High RPM

[Samwng]

Hi there, no worries. It is perfectly normal. The ECU is programmed to warm up the engine faster at around 1500rpm at cold start. That is why, the engine is most inefficient and uses more fuel when cold. However, it should settle down to 800rpm when optimum operating temperature is attained.

 

For fuel injected cars, U should be able to move off about 10 seconds after startup.

This way it warms up even faster but do not rev the engine yet though. Engine wear and tear is at its highest at startup.

 

Use a good engine oil and enjoy your drive!

 

But I heard.. if is in the early morning, got to warm up until 0.8-0.9k rpm then move out the car.. that is the best way to keep ur engine lifespend. Any comment ?

letting the engine warmup(cold start) and settle till 800rpm, WILL NOT extend the lifespan of the engine whatsoever. In fact, one will just end up burning more fuel thats all.

 

Just drive off slowly after start up in the morning. The engine is more efficient this way.

I didn't notice in my handbook on idle rpm.. mabbe later i go read read abit..

 

but then 600-700rpm pretty good... no vibrations thou... quiet..

===================

 

Seems abit low. Maybe u can increase it abit & find a range between 800 to 950 without vibrations.

 

If your car is more than 3 years old, vibrations cud b caused by worn engine mounts.

 

Mine is auto, so I engage "D", put in handbrake with front wheels against the kerb & adjust till less vibrations.

 

Remember to test with all accessories on as that's how it will b when u actually driving.

 

If u not sure how to do, don't try as u might cause car to lurch forward causing some injuries/damage.

 

err..you mention "adjust". what are you actually adjusting here?

 

Thanks
