Okay guys not sure if this has been posted or not but i am looking for some help here.

K here is my scenario. When im driving my car between 1500 to 5000 rpms my car sounds perfectly fine. Once my car is over 5000 rpms i get like a high pitch sordof hard to explain but like a trumpet sound you could say. Also the check engine light is on.

Some people are telling me it could be my muffler some are telling me my catalytic converter could be plugged and others say could be the gasket on my header. Just wondering if you have any ideas or what i could do to pinpoint where its coming from.

All i know is its not until i reach the higher rpms that this happens.

ill try to post a video later incase it will help but any insight for now would be great.

 

at the next meet, for 10 dollars the club can pull the code for you and get a reading on how your engine is running with the scan tool we have.

I suggest you take it easy, and if you ever see the check engine light flashing, pull over and give the car a rest.

Alternatively, you can ask around... I know Tango had a problem with his first header and RRM replaced it. if you can meet up with him, I think he will be able to tell you straight up, if its the header.

 

why not just take it to the dealership and have them inspect it?

you have warranty dont you?

 

i agree, if the car is not modded, then take it to the dealer, if you suspect its modded and has to do with that part, then have someone else inspect it.

 

Definately kicks in when Mivec is pulling. May be loose intake.

 

Try bringing to dealership they can check it for you if not come to meet EVOSoul can plug and look into it I also have one but not as good but I can clear codes and stuff also I'll bring tools to see whats up

 

i have a noise too, its a deep throaty noise during quick acceleration when im on the gas, then it goes away when i let go. not sure if its normal, no check engine lights though.

 

Did you get this sound after installing the CAI? If so it's normal, other than the CEL part. The CAI's make a REALLY loud sound at high rpms!

 

LOL Incorrectly installed Intake??? If you come Wed, either Matt or I can have a look see

Ill be there way early

 

No this has been going on for awhile almost couple weeks after i got my header flex pipe fixed maybe because he went with a bigger diameter flex here is a video you cant really hear it other then in person but i thought id post link anyways.
Might need to turn the sound up a little bit. http://www.youtube.com/watch?v=THgIg3xhkRg

 

Hopefully its not a big problem and evosoul can clear the code.

 

i have a stock airbox on mine and i feel it has gotten slightly louder during quick acceleration recently. wonder what it could be? no cel,, help.
