idle-ing issues, Here Goes again;

[casey-carl]

Hi,
First I would like to thank a couple of people, dom069 your irony and useful tips have kept me going and horney, you input has been of help as well.

First I will explain the car 1992 Golf Mk3 GTI-V8! 1.8
The issue:
Rev's more between 400-800-1100-2000-400-stall
The things done so far:
1. TB taken off and cleaned
2. ISV taken off and then replaced, then new one on
3. Mass air flow changed
4. All air hoses removed and cleaned
5. Dizzy done
6. plugs done-leads done
7. Lambda sensor removed-and replaced

8. all leads checked and wd40 sprayed to check for air leaks.


if the exhust is incorrtly fitted would this casuse an idle problem, I also  removed the dip stick while it was running and this seemed to enhance the issue.


any ideas? thank you 

i'm now thinking it could be the timing belt out and also the TB needs realineing

A GTi V8 ? that's a serious mod!  or maybe you mean an 8V   

Not wanting to jump in on the other guys help..but your getting there for sure,
Don't forget those pesky relays..not sure of the numbers on a 1.8.. !
Water temp sensor..?  and by all means check the timing and TB alignment..

Id check the breather pipes (very common for splitting)  seeing as you mention the idle is affected whilst removing the dipstick.

No problem, I aim to please

In truth i'm supposed to be writing a critical reflection on how ICT contributes to the Personalisation Agenda, so i'm taking any opportunity to distract myself from it, I just happen to be in a bit of a sarcastic mood today

since when has a mk3 gti only been a 1.8?

  Didn't notice that!

[Christo77]

I did..and it's a V8 !   but..you never know with these things,

[casey-carl]

Ok, typo by me? 8v not v8.

have changed the 30 relay the ECU one
have changed the 167 fuel relay

done them as well....

how do you check the timing any pictures or links to follow:

 

[Christo77]

No worries ole chap, we all do typos.. 

Not exactly sure which model you have.. 1.8 !?  anyways, a manual will help..show you how to line up the timing marks on the flywheels for TDC, then line up dizzy rotor arm..again according to your model,

If it's a 1.8 Mk3.. you sure it's not a CL/GL or a Driver spec'd up body wise to a GTI ?
