I have had several electrilcalproblems over last few weeks. I already changed the fusebox. Acctually after that problems bicame bigger. First idiots at Fords who did the exchanged put the loom so the clutch pedal cut one of the thick rad cables nearly making car burs in flames, but just nearly. I fixed it on the roadside and car run fine. Apart from stopping somtimes. It's not connected with anything. every few hundred km's it starts to cut of, stops to react to throttle and sometimes simply dies and wont start for some time. When it happens I can hear clicking sound from the fuse/realays box. It's some relay I think. It's cutting fuel not ignition I suppose because there is no bang bang effect like when ignition problems . I know nobody who has any idea? Maybe its just some poor connection somewhere? Also a few days ago it stopped to have idle revs and made clouds of balck smoke fromm overfueling. Turning it of for like 5 mintes fixed the problem. What can that be? fucked ECU?

Tha car is small turbo + superchips and 1.5 bar boost. I never had any engine electronic problems, so I wouldn't say it's superchips module.
