My Cinq has a really bad misfire when it is cold. Its getting much worse now the mornings are cold and damp. I've tried changing the plugs and leads but it has made no difference. The car is totaly standard - anyone got any ideas what I can try next? The misfire goes once the car has warmed up.

could be water in the cylinders..ala head gasket failure. try getting it compression tested

yer possibly the head gasket is on the way out

yeah I would say head my be on its way out, you having to top up the coolent a lot??

Its not using any coolant at all and a compression test shows everything ok. Could it be a faulty coil pack?

Hi,
Just a quick question, did you do the compression test with the engine hot or cold ?, if the problem is only when the engine is cold it could be a sticky valve......

Could be a coil pack, but as an aside - is the injection light on at all apart from the 2-3 seconds on start-up?

What's the mpg like?

I have got similar symptoms to you. My problem is with the coil(s), causing it to misfire. My mpg is just under 30 at the moment! , getting it fixed soon though.

The compression test was done with the engine cold, and the injection light is not staying on any longer than usual. The fuel consumption seems normal.
The misfire was alot worse this morning, I suppose that whatever is failing is about to expire.
