hey guys just got me 03 evo so I do not know that much about them yet.

hre is the deal the car was running great then I went for a drive today and about 5 min into the drive i noticed the car felt much slower... then I went to accelerate and when it started to boost it sounds like a dying turkey or like someone blowing air through a ballon that has popped like the screeching kind of screaming sound.

I checked the intercooler hoses but didnt really notice anything off.

please help ASAP thanks!

 

the car didnt make a pop or bang noise which i heard could be a hose blowing off

 

^ it did or it didnt? because if if didnt then ur just probably getting a # amount of knocks and u must be pulling timing...idk have it checked...are u tuned?

 

it DID NOT make a loud pop noise the car idles fine etc it just happened all of a sudden.

 

i was just driving it again it sounds like an air leak (high pressure) just going by the sound. it doesnt sounds like a knock at all.

 

you throwing a code?

 

check all you ICP's and make sure all your clamps are tight

 

no CEL which seemed weird as well. Really seems like some kind of a hose leak. I am going to tighten them all see if it makes a difference. anything else you can think of?

 

maybe you should give it a good tune up ,change all hoses, clamps oil coolant fluids ect.... just for piece of mind.

 

I tightened all the IC hoses. no luck. It sounds more like a ballon filling with air it sqeels. but if I accelerate past 5000 it goes away or I can t hear it anymore. Noticable decrease in performance as well.

 

Take off your intake tube and check the turbo for play.

 

guys I figured it out... No way anyone would have figured this out by my description but basically the owner before me put a CAI on the car and must have taken a vac hose off the top IC pipe and had put a piece of tape there to hold pressure. Well I didn't see it because it was underneath but that was what was causing the noise. Now i just need a diagram of someones engine bay that has all of the hose hooked up properly so I can fix mine!

but thanks the car runs great again.

 

lmao...... sounds like a dying turkey???? that was the funniest thing i eve heard...lmao
