Hi peeps. Ive got a 95 Gti 8 valve with 70k on it. It had an ever so slight miss fire when i got it but wasn't enough to notice any difference in drive etc. Only noticeable on idle. It has now developed a more serious fault. On first start up it won't idle atol. Only after a short drive (500 yards) it idles but not very well. It runs really lumpy and is noticeable when driving. It idles not bad but not perfect after a few miles. Also fuel consumption is high. I put plugs, leads, dizzie cap and arm on it and no change.
Then it fixed itself for a day?
And has now went back to doing it again.
Any idea? Please help! I don't want to start randomly replacing parts.
