Can anyone give me any clues on this?

 

My good old reliable 2001 Vaux Astravan (Envoy) played up for the first time today. When giving it some revs I let off the pedal and the engine slows down and dies. Its like the auto idle stability stopped working (if it has it?).

 

This isnt happening all of the time but in a 5 min journey it happened twice. Turn the key and it starts and idles fine like nothing happened.

 

Like I say, first time its happened. I checked all of the vac pipes and connections that I could see but nothing obvious.

 

Any pointers?

 

Thanks

Could be throttle position sensor........or a dirty throttle body, lets of vauxhalls prone to that.

petrol or diesel?

alot of vauxhals have maf issues, simply unplugging it and resetting the ecu, will often point it out at fault. is it an early one? i know the early ones had an issue with diesel being sucked up via capiliary action into the ecu. causing them to drive like a bag of crap, until they die on you. both of my mates that had them had this happen and its why i didnt buy one, amogst other personal reasons.

Hi all, thanks for the responses

Its a petrol 1.6.

The problem did happen after the battery went low (not completely flat) after I hadnt driven it for a while, and I then left it on charge?

 

Doesnt run rough at all, just dies no and again....

Does the engine management light come on?.i think on 2001 models you can still do the 'paperclip' test.check out http://www.topbuzz.co.uk, loads of useful vauxhall diagnosis stuff on there.the paperclip test involves bridging two terminals on the diagnostics plug which causes ecu faultcodes to flash up on the eml in a series of flashes that correspond to fault code numbers.

Its got fuel in it?

A lot cheaper than getting vauxhall dealer to plug it into a tech1 or tech2!!!.......:).
