Re: Rough running at idle and serious judder at low RPM in gear

Yes, that's probably right .. so you're talking about cylinder No4.

Oil on the electrode suggest bore/ring problem, though having said that, a compression test is the only way of knowing for sure.

It may be worth your while asking a workshop for a second opinion/doing a compression test for you. Once you know what the exact problem is you can then decide what to do about it.

Re: Rough running at idle and serious judder at low RPM in gear

Did you find a solution for the rough idle problem? I have exactly the same problem, tried many things but still couldn`t fix it.

I created another thread about it here:

I Have already responded to Mike's question over on Youtube, but for the benefit of anyone else following this thread or reading in the future...

Unfortunately the car ended up scrapped as it lost compression completely on I think 3&4 (Wrongly said 1&2 on Youtube comment) cylinders.

I / we're not 100% sure whether it was piston rings, head gasket or other as my girlfriend is not car minded but the mechanic was Finnish and I don't speak Finnish too well.

I'd definitely recommend anyone with a similar issue taking to a trustworthy mechanic, I spent quite a bit of money in the end chasing small possible causes (even though I was warned directly and indirectly through reading other posts about this), and in the end the estimated repair bill far exceeded the cars value. Quite a blow to spend a lot of time and a fair bit of money, only to have to then scrap the car anyway...

The only real option other than taking to a mechanic would be if someone is willing to lend a donor car to try the parts, or a good scrapyard that'll agree to let you try parts and only buy if it fixes. This saved me at least from wasting money on a MAP sensor for example which wouldn't have helped.

Paul

Re: Rough running at idle and serious judder at low RPM in gear

Let me add the link to the other thread I created about the ongoing investigation of my similar rough idle problem, since the issue was closed but not solved in this thread.

Re: Rough running at idle and serious judder at low RPM in gear

For future reference, my 2000 1.2 8v had a rough idle when I bought it last year. A year and a half later the head gasket crapped out. Replacing the head gasket also fixed the rough idle.
