Hi
A friend has got a Mondeo 4x4 2.0 zetec?? that he wants me to look at

It has a problem
It starts fine and runs fine until it gets to working temp then has a misfire.He said he's changed the leads/plugs.
I will get the car to mine in the week to look at but thought I'd ask on here to see if it is a common thing?

Thanks Brett
