Vauxhall Vectra B 2.0 X20XEV 1999 - Stalls after idling for two minutes - Fixed #

Posted by Nigel Bennett on September 17, 2009, 8:23 pm

Year of Manufacture *: 1999
Engine Code or Type *: X20XEV

Vehicle stalls after idling for about two minutes.
Watching the live data it appears that the air flow
data just drop to zero,the idle control valve responds by opening up and sometimes can catch it from stalling. I've substitute a air flow meter, and no change. checked the wiring connection ect,ect.
Now I'm wondering if the air flow reading is drop as a result of the idle control valve closing down?
Live data shows the idle control valve starting to
"trim" the idle down then stall accurs,has anyone
got any ideals? Regards Nigel.

hi nigel
remove throttle body completely & unblock small air hole under butterfly & clean around butterfly,refit normally cures this fault.

Thanks colin,i carried out a smoke test looking for
a vacuum leak and found one major and two minor.
Fixed them that helped by about 60% the rest was the slow switching oxygen sensor.this was causing the rpm to duck and dive. Regards Nigel.
