on and off engine problem?

I HAVE VAUXHALL ZAFIRA COMFORT AUTOMATIC 1.8, occasionally the engine stops when it runs for a low speed or slow movement, especially when you take off your foot from the accerilator for a short while before accerilate it seems short of power in the process

erg valve needs cleaning,replacing or blanking off

DAVE J, May 2010

Depending on the engine code/ model year, I would say Idle Control Valve/ Throttle Body needs stripped and cleaned and the idle speed re adjusted. Sounds like the throttle butterfly is sticking, and causing a stall. Check that the connections on the air mass meter are tight too, they have been known to be broken or loose causing problems, but that usually brings on the engine management light. Hope this hepls.
