My CSL was prone to being flat out of junctions and jerky sometimes
after lots of there was no faults they changed the throttle position sensor its the one near the oil filter housing.
Its like a new car again

worth a try

Mark- you the man..... u are correct.

We changed all 6 coil packs- 2 which was faulty and all the plugs which made the car run better but still had the jerk on certain times.

eventually we just cleaned out the flaP and housing and changed an air temperature sensor that fits on the inlet housing.

picked up the car today and it is running PERFECT.

Thanks for the advice guys.

THE END

I had the air temp sensor doing that same thing. It was reading something like 40*c.

Glad its all sorted for you bud.

The throttle position sensor and air temp sensor are two very different things.

For the record, our car has 3 throttle position sensors.
