    Calling all mechanics !

    I started the car this morning and it was kind of stuttering. it was stuttering at idle and when I put it into gear and started driving ... it stuttered at certain points .... like at the start of accelerating. Its alsomost as if the power of the engine totally cuts off for a few miliseconds.

    I parked the car up where I needed (10 min drive later). Left it for about 50 mins and when I came back ... it started fine, no problems at all.

    Anyone know if something is packing up or I need to do something to stop it happening again ?

    I put the correct fuel in by the way

    Cheers!

    Happened with mine and it was the coil

    It would help if you told us what car you have and how old.

    Sorry. VW Bora, 2000 V5, only 57k miles.

    clutch, exhaust, gears...
    you need to provide more info

    My Peugeot 306 did this Cyrus. It started spluttering and feeling like it was going to conk out to not driveable in the space of a mile.
    I thought I had blown a gasket or something but the same as Octobergirl I had to replace the coil and spark plugs which cost £200 from a peugeot dealer.
    Get it booked into a garage...

    you shouldn't have problems with the sparkplugs if you service regularly
    it could also be your oil

    Hey, is the OP Miley Cyrus aka Hannah Montana?

    Check your HT leads, maybe misfiring or on running 3 or 4 cylinders

    Take it to your local garage and ask for a quote, hopefully they will diagnose the problem there and then, if its something you can afford them to fix get them to do it, otherwise just say you'll get back to them after you've checked your bank account and go dig out a haynes manual.

    you need to clean the throttle body out you should then get the have the idle reset with vag dig machine but if i was you just clean the throttle body as this normaly works 9/10

    Thanks guys.

    So we have either

    coils - no idea
    sparkplugs - never changed these afaik.
    oil - This is fine, I checked it a little while ago.
    HT leads - whats that ?

    Might be an idea to get AA down here (with a bit of exaggeration ) so that they can pinpoint the problem right away.
    As it fixed itself after a while, I'm guessing whatever it was, it was due to something warming up.

    Its an Automatic by the way if that helps. Same kind of thing happened in my 1.6 Megane many years ago and a mate fixed it. Don't know how and I wish I had now asked as he has moved far far away.

    interesting. How do I do this ? I changed the brakes on the car last week so would say I can do a bit of DIY on it

    Yep - if it's misfiring and you're not sure what you're doing it's best to get a mechanic to check it out.

    Ooh look what I found forums.vwvortex.com/zer…399
    Looks v complex though!

    it could be more complex if it turns out to be something to do with your onboard computer

    Will probably take me another 6 months. I don't really have time to post anymore :oops:
    Apparently I'm averaging 0.92 post a day. Lately it's more like 0.92 posts a week.

    its your MAF - mass air flow meter. google it to find easy ways to check it.

    It may be worth checking the MAF (mass air flow sensor) as these are a common cause of problems on all VAG cars, particularly loss of power; had this happen on my VW golf. I seem to remember you can test if it's this by simply unplugging the small unit (2 second job) to see if it fixes the problem. It's very common and VW/Bosch actually part exchange this part for a new one, and then refurbish the old ones. Google "VW MAF problem" - there will be loads of info on this.

    MAF's seem to be a problem in TDI's. Mines petrol ...

    ah lol, great minds n' all that :-D



    lol yup :thumbsup:

    Mine is petrol, I know it's a very common problem in petrol cars.

    The only thing you know for sure from this thread is that it could be a number of things!

    maybe, but could still be the fault. Normally unplugging the maf will let you know if its the source of the problem.

    By the way, just don't take it to VW! if a part costs £5 they will still try and charge you £500 in labour :whistling: ask your local garage if they have the VAG-COM diagnostics tool, they will be able to plug it in and check for error codes.

    The truth is nobody knows and we're all guessing.
    If you really don't know, then you will just have to take it to the garage and see what they say.
    Come back then with their quote....and we'll judge it..

    Probably nothing more sinister than a bit of damp having an affect on the HT leads etc.;-)

    It certainly isn't the engine oil.

    It certainly isn't the engine oil.



    You never know, certain engines are known for having sticky valves if the wrong grade of oil has been used. That would cause misfires etc;-)

    Then again it could be a faulty PCV or sticky ICV, both of which would be less noticable when the engines warm. I refuse to speculate further as it could be just about anything lol.

    Thanks guys.
    I think I will need to get the VAG-COM lead and software if I am to save money. Can anyone tell me which one I'd need from eBay, as there are quite a few ??

    I have AA recovery so if it all goes t!ts up on the road ... I know ive got backup

    Thanks all !!!!

    im ex vw tec so the first thing i would try is the throttle body clean trace the air pipe from air filter box to the throttle body remove pipe from throttle body with oul tooth brush and carb cleaner or brake cleaner remove the black carbon build up around the body and on the butterfly. refit pipe and start when you first start it it will be hard to start and will smoke for a bit this is the carb/brake cleaner beeing burnt away.

    a little tip try not to use to much carb/brake cleaner and use rag to wipe up exce cleaner

    Mine did this on an old Vauxhall Astra and it was the Distributor that needed rebuilding, wasn't too expensive but it could be a number of things.

    As the engine oil shouldn't come in to contact with the burning side of a valve, it could only be the petrol that caused that, not the oil, or possibly a worn out engine.
