ello!
well i only just got my golf up and running last week and its already playing up again.
after a new clutch, oil sills on the gearbox and rocker cover, oil sensor plug & ICV (which was a royal pain) on the drive home i notcied it was difficult to stop when braking.
when i stopped it was idling at 2000rpm! and slowly rising. miffed angry as i said i recently changed the ICV because it was idling all over the place and trying to stall. the new ICV sorted that and i've been driving about for a week now.
i'm not too sure what it is but somethings telling me its the throttle body but i wanted to make sure it couldnt be something else so has anyone else got some easyer (an cheaper) suggestions for me?
thanks!
p.s. sorry for the double post i just need info asap.

Sounds like a air leak to me

Possible you have an air leak,squirt some brake cleaner around the intake gaskets while its ticking over (well in your case racing) engine revs should change if engine gets a sniff of it and check your vac lines.

+1
Check your vac lines if the abf has them? Can't remember :grin:
Make sure things like manifold, TB, induction pipes are secured properly + have gaskets on them
-
hmmm so you all think its the same thing? i'll have a spray around area's of the inlet then when i get a chance.
how hard is the TB to take off?
-
4 bolts easy.
-
well i sprayed some brake cleaner around the whole system and there was no change in RPM so i dont think its a vacuum leak.
anything else anyone recommends?

Clean your throttle body out as mentioned. Do the revs go up with the smallest touch of the accelerator? (Imagine it was ticking over normal and you went to pull of) If not sticky throttle body or cable? Might not be fully releasing. Just a thought

A air leak will do this too. Start it up and if it idles at 1500 rpm, rev it and if it settles to 2000rpm sure to be air leak.
If it's the throttle body sticking you test that buy pushing the butterfly shut after revving it with the throttle
-
ta people i'll take a look at the TB when i actually have one of those things called a day off i rarely get.
being scottish and slaving away in the hot dorset sun has taken its toll working on the car past month and i'm suffering a bit now haha.

i had a simular problem a few years back. I was cleaning the throttle body after a good ol service (used carb cleaner) and used a tooth brush, anyway while the car was started i would spray it in and then turn car off and use a old tooth brush. Then start it bk up and rev it a few times while my mate sprayed it in there. Anyway what happened was that it back fired out of the throttle body and my face was in the way, lucky it was just a loud pop and i liturally ruined my boxers (lol) turned car of had a nose around and started it back up, when it fired up the revs wer all over the shop. Would rev at 2k then hunt like a c*nt! Phoned someone (creations motorsport in bham) he came out and reset the throttle body by using vag com (diagnostic laptop) and that sorted the problem. This may or may not help but plug in the ol vaj com and see what it shows up!
Hope that helps

That made me laugh sorry :grin: not the best way to do it! thats happened to me in my fiesta but that just backfired through the TB because it was sh!t. ta for the help though i have someone who can get it read but i wont be able to drive to them and thats the problem. so i'll have a go at cleaning it.
if mine does the same as yours (hunting) then i'll have to get it remapped again.

sorted the problem. it was my new ICV that i put on the other week at fault.
took it off and put my old one back on and its started hunting again (which was the problem with the original) so not that bad tbh! thats what i get for buying a pattern part.
