New Focus, New Misfire

I have recently bought a 2000 Focus 1.6 Zetec to replace a 1999 Focus
that had a bad misfire. And guess what, the new one has a misfire now
as well. Great.

The new misfire is much more severe, is constant and deteriorating
fast. It is also accompanied by many electrical problems - the interior
light, heated screens, rear wiper, reverse light have all stopped
working, and the "door open" warning light flashes on now and again.
Also the speedo jumps when the engine misfires (about +/- 10mph).

I read in a previous post that the speedo problem and the misfire could
be associated with the coil shorting, but could this really cause all
the other anscilliary problems?

Anyone had a similar problem? Any thoughts on what may be causing this?

Cheers,

Andrew

Coil pack. Absolute dead certainty.

And yes it can, and worse. Personnally I would NOT start the car now until
you have replaced the coil pack.

You may have already blown the CTU from the HT spikes, you dont want a blown
ECU too, there is only so much they can stand.

Check the CHT wiring too- I assume your car has had the mod to the wiring?

a coil pack will cure the misfire

all them other problems go through the GEM module (drivers footwell)
check all fuses and earth leads, clear any fault codes roadtest then see
wot fault codes appear after that

Re: New Focus, New Misfire

Well, that was easier to cure than the last misfire I had! Coil pack it
was. I put an old one on that I took off my previous Focus whilst I was
trying to find the previous misfire. It's running fine now but
obviously all the random electrical problems still need to be sorted
out. I did hear that it was a bad idea to put on a second-hand coil
pack though - do you think it's worthwhile spending the money and
putting a new one on?

Thanks for your help!

Andrew

When my coil pack failed recently I got two engine error codes and the
yellow engine light. Since the coil pack was replaced, and the engine
light reset, no other problems have been seen. The error codes were
totally unrelated to the actual problem and probably caused by inference
from the faulty coil getting back into the engine management system

Have you still got the other electrical problems or has the coil pack
sorted them out. The engine warning light may be on as a result of the
previous problem. If so, you just need the light to be reset.

Alan,

As expected, all electrical problems except the irractic speedo
remained after I replaced the coil. These were all sorted by securing
some loose wiring in the fusebox, so it appears that it was purely
coincidence that the misfire and electrical problems occured at the
same time.

All's running smoothly for now though. Thanks again,

Andrew
