weird sound when engine at around 2000 rpms

[soup1207]

Hi,

I got my new yaris 2009 about a week. I found there's some cracking sound when the rpm is at about 2000. It happens even if I use N shift. It seems like there isn't any cracking sound above 2000 or below 2000 rpms....The sound is like kekekekekke

Does anyone know the reason for it?

Please....><

[soup1207]

the sound is actually like dadadadadadadadada
it happens around 2000 rpms....
Is it normal?Why?
Thanks....

My cars is quick, whats wrong with yours? You gotta use good oil (motul or total), good fiilter (purolator, wix - not toyota) and good gas (shell) and leave the radio/cd off. There is an electrical interference problem with the stock radio wiring. If you have a 5-spd 3 dr you should get to 60 in the 7-to-8 second range with ONE shift. If you got a 4 door auto you are doomed

im pretty sure my car doesnt hit 60 mph in 1st gear...... and why would there be an electrical interference with a stock car...i think toyota knows a little about putting a car together.

This sounds more like Duh... duh ... duh...DUH!

[soup1207]

TheSilkySmooth and PhilD424,

Do you mean it's normal?
Even my 14 years old 95 previa doesn't have that sound...
I am so afraid and want to have it fix if it's abnormal
I only have the car in my hand for less than a week....

[soup1207]

Today I asked my friend out to see the problem.....
However, the weird duh duh duh sound disappear when I see him....(I drive a while to meet him in somewhere, which is less than 5 minutes driving)
After I home and turn off the engine for a few hours and turn it on again, the duh duh duh sound come back. It actually happen between 1900 to 2000 rpm...It never disappears even I drive it about ten minutes.
Is there anyone know what happen to my yaris?

You gotta check your bov brah'

There was a thread on this a while back. Around 1800-2000rpm, the engine/car shake and you can even hear it.

There is no response from toyota as to what causes this.

I have noticed that in 2nd gear, around 1800-2000rpm, my car is loud, and the engine sounds very bad.

As soon as I give it more gas, and it gets above 2000rpm, or changes gears, the noise is gone, and it sounds/feels smooth again.

I really don't know whats causing this.

I have 50,000miles on the car so far. This coming week I am going to change my motor oil(royal purple with 6000miles on it), and transmission fluid. I am going to also replace the spark plugs, and maybe even the cables if need be. At the end I will also be replacing the drum shoes, and the shocks.

Honestly I say all that but at the same time have $0 to do it all. *sighs*

The stock oil filters are defective - use a wix 51396 or a Purolator. The RP oil doesnt work well in this car. Just run Mobil clean 5000 or 7500 or Penzoil Platinum 5w-30. if you have the bucks run Motul 8100 . You use the wrong stuff the vvti oiling gets messed up and the car runs bad. I Cannot overemphasize how important it is NOT to use the black toyota denso filters for tthe car to run correctly.

And I cannot overemphasize how wrong you are about Toyota filters. They are more then fine, Granpa, or whatever your other user id is/was. I've used the black Toyota filters for the last 62,000 miles and all my UOA are excellent, regardless of the brand of oil.

Sounds like a good idea to just have it checked out. Since it's not a maintenance item, any work should be covered under warranty. Even if not, they are legally bound to provide you with a written estimate before any work is done.

everything in this statement is incorrect..the black oem filters are 100% fine and will perform just as good as the next alternative...heck i use a cummins fleetguard filter in my car..... ive used royal purple in my car in both engine and transmission and i will continue to use it because it works just fine.

Well, you can save what you were going to spend on spark plug cables - your Yaris doesn't use 'em. Must be nice to have a lot of money - the brake parts and shocks shouldn't need to be touched on a car with this mileage.
