A friend has got a 55 plate mondeo 1.8 Duratec he in the garage? Bit of a strange one here's abit about it.

It run's fine until it goes over 30 degree's in engine temp and gain's a misfire when it reaches around 60 degree's engine temp you can rev through the misfire.

Powertrain control module as been tested o.k

Lamba's sensors and readings are good

There is no fault codes at all

Compression tests were

cylinder 1&2 185 psi
cylinder 3&4 210 psi which are quite high

Any help would be great
