For the past few months my Fiat Stilo Sporting 1.9 16V diesel has been misfiring on cylinder 3. The fault code comes up as open/closed circuit failure on cylinder 3. The problem first occured back in October; it disappeared after a short period of time after the AA reset the engine fault light.
It didn't come back again until 6 weeks later, exact same fault code. This time I took it to a local garage; they couldn't pin point the fault exactly as the car was working fine when they had it! But said they would re-wire the injector 3 connection. This seemed to solve the problem; but 2 weeks later the problem appeared again!!
What could it be? Faulty injector? Loose wiring loom connection? Faulty ECU?
Some advice would be much appreciated!
