Celica Forums General Discussion General wierd sound at 2100rpm's

every time i go past 2100 rpm's ( yes, it is EXACTLY 2100 rpm's) i get a kinda metal vs metal grinding sound. i dont know what the hell its from. when i stay at that rpm it doesnt make the sound, its just when i accelerate through 2100 rpm's. do you guys have any idea what it is? i wanna have a clue before i take it to the dealer, im still under warranty, so hopefully it will be fixed. so you know what it is?

ttt...anybody have an idea of what it is?

My GTS does the same thing at about 1900 rpms. I took it to the warranty and they couldn't find anything wrong. They said its's probably my CAI. It started doing it a few days after i put it on. After I clean it it goes away a little bit.

that happened to me rember?, every time i reved past 3k exacty it sounded like a metal ticking or grinding sound. rember what happened next? i needed a new engine...covered under warrant of course, i think you should have your mech give it a compression check it could be a bent valve.

check your hood release latch on the interior, if it jiggles, you need to go thru the TSB

yea my gts will make that sound also but jsut at that point then it will stop lik 2kto 2.2k

hmm.. does it tick or knock at idle?

I'm telling you, check out the hood latch.

it's a metallic vibration/rattle that happens at a certain frequency (engine speed)

mine did that too...
so i reset the ECU then start driving the car smoothly for like 3000KM... then it goes away.

i'll go tighten it and see if it helps

ill check mine out too

my friends car made the same noise at around the same rpm. his is an rsx though. right when he accelerates makes that metal to metal noise, like something is vibrating or loose. it was the inner axle. thats a common rsx problem. if nothing else works, try to check the inner axle.

i had the same problem. sounded like a metal to metal grinding sound after about 2000 RPM. Brought it to the dealer and sure enough i need a new engine, just found out today that i need the new engine, still dont know what caused it or what broke. Whole problem was covered under warranty tho.

does it sound like marbles? mine makes a noise like that at lower RPMs but it sounds more like marbles

Same thing here but it dissappears after 2000 rpms more like a rattling sound like marbles!

It might be knock which may have been caused by poor gasoline. Let us know if the problem persists after refilling with higher quality gasoline.

ive used 93 every fill up and still ahve it i greesed the hood hinges and it still does it

when i had my jetta i was at www.vwvortex.com [vwvortex.com] all the time in there fourms and i remember them talking about on the 2.0 4cyls that the heat shield for the header would vibrate and make a noise at a certain rpm maybe this is the case (i had the vr6 so i never heard what it sounded like)

Why not pop the hood and have some one hold the car at 2100 while looking for the culprit?
