#1: Juddering...running out of ideas :( Author: Mr-Tigger, Location: EssexPosted: Sat Mar 02, 2013 11:11 am ---- sorry for the overload of information here but figure the more the better. so the GTI has a lumpy idle when cold but smoothed out once warm and dropped to 800rp, and held steady no problems.
Took it to surrey to see old man Krisb to get the cambel tensioner and water pump done,since then it is continuing to run lumpy when hot. idles fluctuates a minor amount (maybe 150rpm) down,and the juddering isnt constant but its there at least every few seconds but a lot gentler.
Ive cleaned out the plug-wells and plugs (stupid NGK but they were in before anyway) two are slightly white/grey and not smooth. Also went to clean out the throttle body but it was pristine almost. Have finally taken it for a good raggin with some redex (i know,before the ney-sayers start lol) but its still lumpyish.
It has thrown up the cat/anti-pollution fault twice,both times clearing itself after 20miles general driving,once before and once since cambelt was done.
Any suggestions before i end up forking out silly money for machine-time to test it?
forgot to add,does sound like its blowing a tad at the exhaust and does give a bit of a wobble when ya stop the engine but not all the time
Thanks guys

#4: Re: Juddering...running out of ideas :( Author: Mr-Tigger, Location: EssexPosted: Sat Mar 02, 2013 1:47 pm ---- hopefully enough to cause this judder/misfire,but not enough to have buggered me coilpack as i forgot to check whether it was the sagem or bosch.....though tbh didnt see an obvious brand anywhere on it

#6: Re: Juddering...running out of ideas :( Author: Mr-Tigger, Location: EssexPosted: Sat Mar 02, 2013 2:46 pm ---- yup,he did it,lucky lad found out hard way it was floating pulley too lol. another mate said was timing right but it did it before cambelt was done when cold,only now keeps doin it when warm. gna get ripped off at halfords tomorrow and see if that does the trick

#8: Re: Juddering...running out of ideas :( Author: Mr-Tigger, Location: EssexPosted: Sun Mar 03, 2013 12:26 pm ---- waiting to get that sorted tonight hopefully,but had a look at few the main culprits. cleaned throttle body,new plugs,cleaned ICV buuuut didnt realise how it worked so put it back in without testing if it actually moves lol. DID find a small hole in exhaust in the join between backbox and centre pipe. and spraying carb cleaner didnt reveal any obvious leaks on intake seal,though didnt have the a**e to check for cracks other than areas visible from above. been a fun day for a n00b lol
