I had a faulty ECM which was causing lots of problems. I obtained a recon unit from USA, the problem now seems to be with the prom. My car is Euro spec with no 02 sensor and the USA spec prom is giving 02 fault. I tried to fit the original prom but the ECM is now giving faulty prom codes. Can anyone suggest where I may be able to obtain a new prom which is programmed for the Euro spec cars? i.e. no 02 sensor. Plan B is to fit an 02 sensor, but the car has no wiring and and no pins on plug, so not keen to go that route. Although the car is driveable the check engine light comes on and car has performance issues.
