FIAT TIPO MISFIRE?

My 1995 Fiat Tipo 1.4ie, with 90,000 miles, has developed a misfire which only happens from cold, and persists for the first half mile or mile or so. After that it settles down and runs fine. It is at its worst the more trottle you give it, being gentle for that first mile minimises the problem. It has had the head skimmed, new HT leads and has just been serviced. Can anyone tell me what I should check please. Thank you.

I'd start with distributor cap and rotor....

Coolant temperature sensor? (If its fitted to this one, I think it is)
On (more modern / less old) cars with a bit of electronics, the CTC acts like an auto choke, so if its duff, the car will underfuel when cold making it a PITA to drive until it warms up a bit.

On the plus side one of those should be easy to obtain for between £10-30
Once you can get to it, the little so and so just screws in

coolant sensor sounds like a possibility, though it's t'other way round on the K series, if the sensor is disconnected it overfuells

coil pack/packs as well might be suspect.
