Hey guys new to the site just joined
Im scratching my head abit
I have a 91 mk4 xr3i efi and keep getting an intermittent misfire 20mph 2nd 30mph 3rd and so on any ideas as to what this mite be as checked all the obvious

 

Sounds like a plug or lead to me mate. Or it could be a sticky valve. That can cause a multitude of unexplained faults.

 

cheers mate will have another megta search and swearing session tommorrow and then update as an remedy lol

 

plugs and leads would be my first buy

 

done plugs leads etc and got no change and now got major headache as changed fuel filter but cant get the bugga to seal at the banjo end any ideas welcome
