noise during acceleration??

[marcus]

i got noise during acceleration a whirllllllllin' sound. on my old car that sounds like an overly advance timing setup.. and it need to be retarded a bit or run a higher octane fuel...unless this is normal for this vvti engine .. anyone!!!:iono:

is this the celica or a yaris?


in my yaris i can here that running up through the gears with the windows closed or driving beside a Jersey baricade with the window open.

[marcus]

its actually the yaris..i tried to see if i can adjust timing. but it seems like its all electronic...*sigh* still sounds like the timing is too advance...i dont know..??

[rage2]

the timing is not too advanced. sigh.

[marcus]

well unless that noise when accelerating is normal..chain belt maybe...it bothers me..

[firefly1_0]

take it back! if you think its an issue, explain it to the service department.

[marcus]

well see after break in period..its only been 700 km on it..

[Katana]

Μaybe the chain belt, as mentioned.

[jmjonesey]

I feel your pain, it sounds like a large tambourine in there or something, definitely sounds like the chain or something vibrating

[marcus]

well find out soon boys..

I have also had this problem for a while. I havent had time to take it in yet though, Please post what you find.

Hmm... noise during acceleration. I'm guessing it's the sound of the piston firing. :wink:

Does the Yaris have a timing belt or a timing chain? (pretty sure it's not a "chain belt" :laugh: )

~YR

[Nimble]

chain

[redyaris]

mine sounds like a sewing machine upon acceleration...Singer to be precise.

[marcus]

its actually a chain belt for this yaris!! so i figured that was the noise

the yaris has a timing chain, no currently produced toyota engine has a belt except for the 2uz-fe 4.7.

[marcus]

well we i know its a chain.. its actually the noise when accelerating is what were trying to figure out...could be the chain making the noise..

You should replace the washer fluid with high performance red super temp, it's great at keeping the washer fluid cool when the 105.2hp is cranking away. That'll fix 'er.

[marcus]

washer fluid??? you mean the rad coolant/engine coolant>>

[Nimble]

Nope, I meant the washer fluid. It's a highly underrated, intricate part of the engine's function.

[marcus]

ey nible.. ur getting the coolant mixed up with the washer fluid.. totally different fluid.. one for the engine (coolant) and one for washing your windshields. (washer fluid)..

[Nimble]

Lol, you are ruining it! It was a j-o-k-e! lol :)

[marcus]

oh i see it may not work here you might wanna do that on the honda fit forums...lolz

right, the reader of the joke has to be able to think for the joke to work. :biggrin:

[marcus]

well i meant is that we dont get weird comments is here..so i figured u were serious..just trying to help bro..

[marcus]

anybody else notice the engine noise on regular gas and less noise on premium..when accelerating

[Yaris Revenge]

Every review I've ever read about buzzy engine noises seemed to blame the use of a timing chain. That said, IMHO timing chains are much more desirable than timing belts, despite the noise. Replacing a timing belt (usually recommended ~60k miles) is an expensive to-do, and should you ever have one snap on you, it basically FUBARs your whole engine... pistons and valves get up-close and personal, and all hell breaks loose (literally). Toyota timing chains are so cool, they don't even require maintenance! (or at least that's what they told me about my Vibe/Matrix). :thumbup:

As far as the regular vs. premium, the only difference is how quickly it detonates. Premium burns just a tad slower and more smoothly due to the extra octane molecules tacked on the end of the molecular chain. Regular burns quickly, resulting in more of a "pop" combustion. Maybe that's has something to do with it? If I'm not mistaken, most fuel injected cars have "knock" sensors to detect pre-detonation and electronically adjust the timing to compensate.

Just a shot in the dark since fuel and the timing chain have already been disgused- What about the A/C compressor? They can make a whirring sound when the compressor clutch is engaged. Run your car with both the A/C on and off and see if it goes away. Remember, even if your A/C button if off, it is still on if your using the defrost airflow. Turn the fan switch off to be sure the clutch disengages.

[marcus]

i dont have my ac on... i may unplugged the battery maybe ecu will reset..otherwise..ill bring it in.. first tank was regular gas 87 octane from dealer..i heard the noise on acceleration but i switch to premium for the next 3 tanks..didnt notice it then..just went back to regular and its quite noticeable..hmmmm engine knocks...id say either timing too advance or antiknock sensor not working. well find out soon enuff..

[marcus]

got the same thoughts about this.. could be the antiknock sensor not working properly...ill keep you guys updated..

men this noise during acceleration still botherin me. specially when the car is loaded its more noticeable.. doesnt anyone notice this. is it normal due to 105 hp ior is it the timing not adj or faulty air sensor .. anyone??? arghhhhh!! hope the cone filter im putting on soon fixes this. otherwise?

[sherryberry]

I thought u were going to take it to the dealership? did you ever do so?

[marcus]

i did they said it sounded the same from the other yaris they have in there,,,*sigh* this cant be normal..

I thought u were going to take it to the dealership? did you ever do so?

[Nimble]

It's the turbo whining up producing 80 wheel hp.

[marcus]

yah i bet thats what it is..or the flux capacitor building energy for 88 miles per hour blast...:thumbup:
