Eventually stalling or revving erratically . I have changed the spark plugs , the air filter and now ready to change the petrol filter, all coils are new except 1 but it is working fine. There are no warning lights or any codes popping up on my odb reader , cheers guys for your knowledge......

    Ignition coils were a big problem. A professional grade scan tool allows key engine sensor data to be analyzed right off the scan tool without having to do intrusive testing at each sensor. Live sensor data would allow you to see misfire count per cylinder,and fuel trim figures.
