Hi I have a 1.6 zafira club petrol, recently I have the eml come on, juddering as if fuel blockage. Changed front o2 sensor, full service including fuel filter, cleaned egr valve out but still light on and code p0136? Has this car got a rear 02 sensor pre cat or not if so could someone tell me the location as I cannot see it! Any help gratefully received.

With the juddering I would look at plugs and ignition leads . Could be breaking down under load and subsequently unburnt fuel in cyl .Check wiring to o2 sensor .

Thanks for help just had full service, plugs, filters, oil etc just bought second o2 sensor hope this sorts, could it be coil pack?

Coil pack can short / track causing the symptoms you're having .
