if its going up & down could either be a vacuum leak or ICV could be getting clogged up with crap

you can do a pin test on it coz vauxhall will charge the earth to plug it up to the computer

i think the relevant page is on migweb.com

this will tell you the fault caode it has registered, then you can look it up on the same site and diagnose the fault

good luck dude
