Title: 8v GTi - stalling without throttle applied
Post by: Guy on 01 October 2009, 20:10
so..

the mk3 starts (once you press the gas pedal)

let go of the gas pedal and it stalls immediately, it does this hot or cold...

have changed HT leads
the two relays were changed about a year ago for genuine VW ones
the TB has NOT been cleaned out - it WILL be tomorrow with the help of horney
spark plugs will be changed tomorrow

it used to stall ONCE when it was started (after running for about 2 minutes) - and was fine for the rest of the day after that... then it developed this fault

it has done a couple of 500 mile round trips recently and i think these have taken their toll

is there ANYTHING else that I should be checking in order to get this b!tch up and running pleasings.. it is completely undriveable as it is.

(and no... i haven't searched... as I am fcuking tired and p1ssed off from cycling everywhere as the mk1 is knackered too)

You got the bit for the MKI yet? If you have we cam do that tomorrow as well.

As for the III we'll clean the TB, check all the sensors, check all the vac pipes and see how we get on.

You got any carb/brake type cleaner? If not I can pick some up on the way over.

Yeah, i would go with cleaning the tb, made mine run 100 times better, but also clean the vac pipes, as mine were litterally blocked with rubbish.

Failing that it would seem logical its a fuel supply issue, so maybe a sensor is broken somewhere.

I would offer the use of my reader, but ur are miles away.

Is the throttle linkage thing touching the idle switch when closed?

cleansing wipes came in very useful - thanks you  :smiley:

Nick has just left after an afternoons tinkering...

cleaned out TB and airbox - still not working after this without the throttle applied
removed air mass sensor - then ran very rough, gave it some beans and it coughed and spluttered and untwisted its knickers when the sensor was plugged back in... happy days

potential problems -
1. found whacking great big hole in underside of oil breather pipe - this will be replaced but Nick duct taped it as a precaution
2. automatic throttle adjuster makes a funny whiny noise when the engine is switched off... Nick will be along to give a more technical description of this

is yours dependent on whether it is hot or cold?

my problem was regardless of whether the engine was hot or cold

its regardless. even when the cars warmed up, after i turn ignition off and go to fire it again, it needs the throttle applied for the first few seconds. did u manage to sort it then?

yeah... mine was needing the throttle applied constantly, not just for the first few seconds, otherwise it would die instantly, hot or cold

but it is sorted now... good clean up of the air intake system, and removal and reconnecting of the air mass meter was all it took...
Title: Re: 8v GTi - stalling without throttle applied
Post by: av_golf on 06 October 2009, 12:52
replaced the coolant sensor but problem still persisting, air intake was cleaned also. will try the last bit you said but i really dont think it will solve the problem. any other ideas?

does it flat 5k? if so check your ignition timing

Hook up a pc with Vag Com and read the fault codes. Mine was the Throttle position actutator on the TB. Removed and cleaned the cable that goes into it with electrical contact cleaner, moved the cable away from the hot manifold towards the injectors. Hey presto, sorted.

(£15 for the cable on ebay, software comes with it. Or if you want download for free of their website.)

He means does it not rev past 5K if so your timing could be out. :smiley:

it does rev past 5k and has no flat spots what so ever. also the idle is a bit funny, kind of revs slightly up and down on its own. checked the ISV and thats all in good working order. who said these golfs were reliable hey? :laugh:
