3s-GTE ‘putt putt’ sound

Post by platmatt8 »

So I notice when at low speeds with low revs in 4th / 5th gear I notice what I can only describe as a ‘put put' sound from the air filter area.

Is this normal?

No it's not that, I know that sound.

It's like the engine is coughing.

It's a generic stainless steel mesh cone filter.

Is it stuttering/misfiring too? My first thought would be water in the spark plug chambers (if that's what they're called :lol:)

Are you sure it's not a leak from the exhaust manifold or turbo gasket? A slightly loose manifold or a small blow on the gasket can cause a slightly whispy put-put sound.

Its not misfiring as it pulls very strongly, but in 4th and 5th gear it doesn't like trying to cruise or pull way at lower revs 40 to 50mph.

I've changed the plugs, and lambda sensor.

It's not all the time, just 4th and 5th gear. Sometimes on startup it does a small put put but.

I've just refit the stock exhaust with all new gaskets and VHT silicon sealant.

Under power, well I say that but more like half throttle if that makes a difference.
