Would have suggested coil pack but you say it has been changed .Might be worth getting it scanned and see if any fault codes .

Crank sensors can fail when heated up but causes engine to stop .Cant remember if it was that car that had problems with cam sensor wiring .

This explains the fault , (someone else on another forum)



Vauxhall zafira 1.8 idle / Cam sensor fault



Afternoon all. I replaced the cam belt on an 03 plate 1.8 petrol and now it's rough idling and bring up cam sensor fault. I rechecked the timing, (spot on) but did notice the wiring in the sensor had bared wires so I replaced, but still the same. Does anyone know the trigger wire colour and what voltage you are meant to get. I have one earth 5 volts on one and only 2.5 coming out.

Thanks.

Zafiras are prone to lots of gremlins and false error codes. Trust me I've been thru it. Changed everything and still wasn't right. Turned out to be the engine loom connector. Its on top of the engine on the right hand side iirc. It has bad connectioins inside making the edcu think everything is going crazy.
