156 1.8 ts misfire
Having a nightmare with my 2001 156 1.8TS sportwagon. The cambelt snapped earlier in the year, after it was repaired the sensor for the radiator fan stopped working and the engine got pretty hot, a slight misfire started, the car then went back to the garage where everything was checked, the sensor had been fixed by this point but my mechanic couldn't solve the misfire, I have replaced spark plugs, coil packs and injectors. misfire is now worse than ever, fault codes come up on 2 cylinders (3 and 4). The car is undriveable and has no power. An electrician has also looked at the plug on the Ecu but can't see a problem, Please help!!
