exhaust manifold red hot

[absolut]

i own a 95 integra ls. my exhaust manifold is getting red hot when i drive for a short period of time. the dealers say that nothing is wrong with it. but i dont think it should be glowing red.
can anyone tell me what could be wrong with my car?? ;ScratchHe

Have you checked your cat?

[David]

are you turbo charged? I have herd of turbo manifolds doing that but never on a N/A setup

[HONDA GHANDI]

More info on the setup please

[Weston]

It happens to my turbo Integra, but only if I'm really beating the crap out of it. I never checked to see if it got that hot when it was NA.

[HONDA GHANDI]

The EGT's shouldnt get hot enough to make the manifold glow if it basically stock.
If it is running a little bit lean it may glow when hammered on for long periods of time.

[ryanman]

IF it's stock and it's running lean in CO then you got problems. "Normally" vehicles tend to run a bit rich up there.

[HONDA GHANDI]

right.

[hoffman]

i miss that glow after a brisk drive

[Bedlam]

You should see the manifold from the Evo after a bit of abuse...good times. :) I could have read a book from the light that thing was putting off a few times I think.

It depends. Is your motor turbocharged? If not, you've got something 'bad' going on. Clogged cat converter, clogged injectors, hosed ECU, something.

If you are turbocharged, then yes - it's "normal" for the exhaust manifold to have a nice glow to it after a spirited drive.

my moneys on the cat :fu:

Well, hopefully he posts on his setup soon.

[ricewizard]

possible t-belt/ timing does it run good or sluggish?

its sluggish but not running horribly i know nothing is wrong with the timming belt

no turbo completely stock and y would it have anything to do with the cat?

i heard that it might have something to do with the intake and/or the throttle body.
its defintely running to lean
im not sure if its because of the temp outside or what
anyone know anything about the intake ????? ;NutKick; :guns:

[ricewizard]

only if its a vacuum leak but to cause that it would need to be a big one. does it idle?

what do u mean does it idle?
how would i know if i had a vacuum leak anyways???

[STIBungy]

He means does it idle steady or does it oscillate?

It's definitely not normal. I'd like to know what Acura dealerships told you it was fine. :guns:

If the cat is plugged, the exaust will back up, heat will build, and the manifold will glow....... thats why turbo mani`s will do that... the turbo is actually a restriction on the exaust at times, so heat will build a little higher then normal.... some one correct me if I'm wrong (I know this is a pretty simplified answere, but, well...........................................)

[absolut]

plugs are telling me its running lean
i dont think it deals with the cat
i need to know y im getting to much air or not enough fuel

if the cat is not flowing, the hot exhaust can not escape.
