My misfire
« on: 18 July 2007, 11:34:57 »
As previously reported my 2.0 is missing on no.1.

I have replaced plugs, leads and DIS pack,  there is a good spark to block but still no.1 is not firing.
Pulling off the lead at idle makes no difference on that cylinder.   Plug is wet (dries off so I assume fuel) and looking down through the plug hole looks wet too.   Idling is rough (due to 3 cylinders) and isn't pulling under load, but otherwise will rev up to redline.

Having replaced the whole HT side, I am stuck. (No EML on - is it still worth doing paperclip test?)

Any ideas?

Cheers,

Ian

Mark - how do I do a compression test?  Do I need to acquire a compression tester or is this a garage job?

TB - err quite a lot.  The old girl has done 186k, although had a recon head at 60k.   Looking down the plug hole does look quite oily.

The second version is better if you can stretch to it, the push on ones can get a bit hairy!

If you get one or loan one then post up and I will offer a quick guide on how to use it ....

Thanks Mark.  I've got no problem buying one (any excuse).

I hesitate to mention this as I'm not sure of it myself, but the coolant level was a bit low.  I've recently changed coolant so may just be it needed topping up.  I've not been using the car since my mrs reported the problem so cant really track it.  Also got the impression the exhaust output was quite moist.  But definitely could be I am imagining things scratching around for a theory.

I've got a compression tester that'll do the job if you want to borrow it, Ian
