Golf GTI Misfire / Judder

[PaulGTI]

PCV valve could be knackered ?? have a search on here for it. Or if any of the pipes to / from it have a hole in them this can cause vacum loss and cause judder

I haven't pulled it apart yet to check the PCV properly but will have a look to see what state it's at the weekend. Thanks for the help and advice though :)

It's not resolved. Saturday while drive from a friends wedding to the reception the car almost went into limp mode. Pulled out of a junction and accelerated to 60 then it wouldn't accelerate any more, couldn't get it to rev past 2500 for about 3 miles and was juddering again! This is getting very frustrating to say the least. I have how ever fitted a forge catch tank today so maybe that might help things. Hopefully!

What would ppls thoughts be for this on changing the rear pcv breather valve

[raptor_tom22]

Well 2 days down with the forge catch tank and all is ok so far. Fingers crossed this may have solved it but will update again in a week :)

Have a thorough check of all your vacuum pipes.

Good Luck !

Problem is is on going :(
Saturday night popped to the shops and pulled out onto the road and it happened, would rev past 3000 and was very slow to get to 3000 rpm, lasted for a few hundred yards and then was back on point with no problems. Someone has suggested the cat but not sure how trust worthy that may be. Still no lights coming up on the dash and nothing coming up on the diagnostics. Anyone got any other suggestions?

Did you sort it?
Throttle body perhaps.

Still on going, I tried millers injector cleaner with every tank through the summer which seemed to clear it up but it's back. It's making me think it could be an injector problem. Any thoughts?

Thought I would resurrect this as it is precisely the same issue. It's probably the same damn car! :)

It has been getting worse, sometimes just a couple of judders then runs fine. Today it was in a right state wouldn't rev jumping around, wasn't good. Getting it back to the garage tomorrow, although I'd put money on it that il start it up and drive it there without a single hiccup!

So far dv has been replaced full service plugs etc coolant fans.

Really driving me mad, it's my other halfs car who is 5 months pregnant and is very worried to drive it now.

Thought coils but when it's running ok it's fine good mpg certainly moves along quickly too. If a coil was dead it would be running badly all the time. Also apparently no faults read...

If anyone has any ideas? Getting a bit stuck with this now. Only had it two months starting to wish I hadn't bought it...

Cheers

Bringing up an old post.

I'm currently in the same position too.
- No faults recorded on VCDS
- Coils etc all checked

Cam chain tensioner?
