My mk4 golf 2.0 gti has been off the road for 2 weeks now. it started running slightly lumpy and there was a lag when pulling away from junctions. put new plugs and leads on - no difference.
i then put a diagnostic reader on it and it can up with lambda sensor. so replaced that, the code went but still running terrible. also changed the cat as there was a tinny rattle, it wasnt ne of the heatshields and got told it could be the cats thats collapsed thats why its running lumpy cos emissions can get out!!! it is now running worse than ever. feels like its running on 3 or even 2. no power in it at all!!!!! had it at a garage and they think its sumthing to do with the pistons as its been using quite alot of oil and the new spark plugs are covered in oil. just put diagnostic on it again and it is coming up with:
- multiple misfire detected
- misfire in cylinder 1
- misfire in cylinder 2
- misfire in cylinder 3
Anyone else had the same and what was the outcome. thanks
