Why does my 1999 1.8litre Vauxhall Zafira keep stalling only when from cold?

When I start my engine and drive to the first junction the engine will stall and cut out and takes about 20secs of turning the engine before the engine restarts. Drive 100yrds to next junction and same happens. After that the car runs without stalling apart from Kangarooing and juddering at low speed. Engine management light comes on and off. removed the EGR valve and it does not appear blocked visually. Even tried a blanking plate but no difference. Engine management light permanently on without EGR valve.
Someone posted running an wire from the air flow meter to earth which solved their issues. The engine only cuts out first thing from cold but does not cut out when at speed like some zafiras. Any ideas what is causing mine to only cut out when I start it from cold and why it judders and kangaroos?

Thanks
