Hi, I have a 1.2 Fiat Brava 2000 w plate. It is misfiring when cold. Runs normally when warm. The plugs and leads were replaced within the last 6 months and it has been fine until the last few weeks. The coil winding resistances match the figures in Haynes so seems ok.

Internet search has thrown up the possibility of minor head gasket leak with coolant seeping into the cylinder(s). Oil looks normal. Any suggestions how to check for this? Has anyone had this problem before?

First thing to change would be the coolant temp sensor if it runs ok warm.
Then be worth looking at crankshaft (or camshaft) position sensor if above doesn't fix it.
Don't rule out the plugs and leads though
