Hi guys please help ive had my 03 arosa s 1.4 for over a year and recently it gained a bad missfire problem , it was down on compression , ive had my head rebuilt with new valves , lifters , gasket and all sorts , this fixed the missfire problem but still left a power loss issue , when starting the car runs lumpy as hell and usually cuts out , sometimes it wont even tick over it will make a lumpy noise and cut straight out , when it does manage to move there is now power what so ever and the car shakes a lot , making a noise through the exhaust , my car has managed to drive before without a key ? Soo can anyone help ? Is it the ecu ? Cat blocked ? Lamdba sensor ? Temp sensor ? Or something else , ive spent a lot on this car and nothing seems to be working
