Re: Why do my revs keep dropping? (Mk3 Golf GTi)

#1

Hi, I'm having similar (very occasional) problems with my 1996 Mk3 GTi. I
read somewhere this may be down to the Idling Stabilisation Valve needing
cleaning, but not being mechanically minded I haven't yet tried whipping
this thing out yet & having a look.

Anyone else had this and solved it? Please give (simple) instructions & I
can give it a try.

Cheers

Neil

Hi,

I have just starting experiencing a problem which I hope someone can
shed some light on - when I'm slowing my car down, at a junction for
example, and I take my foot off the accellerator, the needle on the
rev counter drops way down before popping back up to normal idling
speed.

It's ok if I'm just easing off the gas to change gear, then bringing
the revs back up again, but on occasion, when I'm not immediately
bringing the revs back up again, the needle drops to 0 and the car
stalls. It's not like it comes to a juddering halt or anything, it
just dies, but always starts up again without any problems.

I was thinking it might be a sensor somewhere, but I wouldn't know
where to start checking, so if anyone has seen this before, or has any
ideas, I'd be very grateful.

Thanks

GW

Well, I started having a look at this last week, but Hayne's BoL
wasn't too clear and I wasn't sure where this valve is. However,
when I took the big air hose off where it connects to the top of the
engine, there was a whole mess of crud just this side of the flap
which get's opened and closed by the throttle (how technical am I?).

The air filter was spotless having been replaced a little while ago. I'm
guessing I may not have put the filter box together properly and air was
being drawn from above....just as well the miles are knocking on I guess
as there's a little oil about this side off that flap I mentioned, which
seems
to have caught all the grit - other side of the flap is nice and shiny.

Cleaned it all up and checked the filter box, and it's been fine since.
