Hi all

A few weeks ago, I cleaned my intake manifold with clean brake without dismounting it. The only part that I dismounted was the throttle body, and I sprayed the interior of the intake mani.
Since I hear a noise (a "pschit" like turbo ) between 2500 - 3000 rpm and between 4500 - 5000 rpm.
Did that already arrive at the one of you? How to cure it?
Thank you by advance for your answers

Sorry for my english...

not quite understanding what your saying here.

do you have an aftermarket air intake? cause mine makes that noise.

FanaHONDA

It's an OEM intake manifold
It's since I cleaned it that it makes that noise...

I don't think brake parts cleaner is combustible. You're supposed to use carburetor cleaner and have the engine running, or else you can hydrolock the motor. If you're going to use brake cleaner, you have to remove the intake manifold from the motor first.

I'm not sure about your noise. Is it a constant noise when you keep the RPMs in those ranges? Or does it just make that noise for a short time when you reach that RPM?

Keith Pierson's bitch

how the car running otherwise? is the idle different?

FanaHONDA

suspendedHatch, yes it's a constant noise when i keep the RPMs in those ranges, and the car and idle are normal.

would it have another thing to do before i must re-disassembling the intake manifold?

listen closely to your IACV and see if it comes from there

I already tried to listen closely the engine during accelerating (with my car staying static) but there was no noise...
I hear it only when the car's running.

I will try to re-listen closely the IACV.
If the noise comes from it, what should i do? clean it

Thanks for your replies all

try cleaning the IM with carb or tb cleaner.

also take off the iacv and clean it as well. see if that helps

FanaHONDA

ok 93egsedan, i will clean it this week end. i will tell all of you if that helps or not.
Thank you guy
