    Can someone point me in the right direction please.I'm definitely a points & carbie guy so a little out of my depth with this electronic stuff.

    My daughter has an 04 VY 3.8 ute which has had issues starting and idling and after some nagging I had a look .The first thing I noticed was the IAC sounded odd .My son has a vs wreck up behind the shed so I thought I could pinch one off that fitted that starts up once ok then find it has screwed out the plunger in the valve completely ,thought it must be stuffed went to wreckers got another it screwed this one out too. Being a slow learner I went and got another same thing .Am I doing something wrong or is there something I'm missing.

    You need to get the right IAC from a VY. I had the same issue with my VX.

    Possibly wont hear an answer back on this one but I'm curious to know did you fit and try the second IAC motor? By your description it sounded like you may have fitted the plug, left the motor dangling and switched on the ignition to see what might happen. If the latter is the case, to my mind the software at startup would wind out the stem looking for its fully seated position, then wind back an amount to allow enough air bleed to give an even idle speed. Correct me fellas if I'm wrong here on how this little beastie operates. Cheers.

    Did not try ignition without it being firmly screwed in but the new one worked fine
