A pal of mine has a 2001 Focus Focus 1.8 Zetec and lately it has developed a problem with cutting out at random times while driving.

He says it doing it when going into junctions or turning corners so i'm guessing it's happening when the clutch is in.

My thoughts were along the line of an air leak on the inlet side, maybe the gasket, but i'm no mechanic.

He's had it on the computer and no faults were detected.

Any ideas guys?

Cheers
