Pug 20 1.6 GTI sludge in throttle housing

Hi,

I recently had a problem which evidently was due to sludge in the
throttle housing.

The symptoms were failure to acclerate and failure to pull. An
intermittent problem.

I had the problem diagosed at a garage and the mechanic has cleaned
the housing and the breather pipes.

I note now that occasionally the car idles at about 2000 rpm. If I
blip the throttle it settles down to a lower level.

I can't see any problem with the pipes or cables around the throttle
housing.

I was wondering if some wd40 sprayed onto the cables at the throttle
housing might help.

This problem is intermittent, and a blip on the throttle always
returns the idle speed to lower level.

The car has always idled on the fast side.

Any comments welcome.

Thanks.

Carb cleaner or u might be able to use wd40 and rub it with your fingers then wipe it off with a bit of rag ,worth a try..

 

Hi,

Thanks for responding.

The housing looks sealed in.

There is a breather pipe (narrow) connected at the top, and a larger
hose connected to the metering system.

It looks like this larger hose would have to be removed to clean the
inside of the housing.

Bit of a job.

Best wishes.

I intend to try and clean out the part of the breather that includes
the oil filler assembly.

The problem is that the neck takes a sharp turn. Any idea how I can
clean below this bend.

The sump is full so I can't run any oil down that would clear this
part of the breather.

Thanks
