VS Calais revs drop at idling speed

[vsuterus]

Hello,
My VS V6 Calais when in a carpark or putting from reverse into drive etc loses its revs and acts like its going to stall at lower speeds. It never does stall, but, loses revs and then comes good. Would this be a faulty throttle position sensor or possible a fuel related problem? no error codes come up when checking the computer, and a few things have been replaced on it - coil pack, leads, spark plugs, O2 sensors, computer, before I got it. So it doesnt leave much else! Any help greatly appreciated!

more like a IAC valve, i got mine replaced, but you can take your throttle body off, take the IAC valve off the throttle body, and screw it back to 28mm (pretty sure thats the measurement), but also give the throttle bohdy a very good clean (preferably take it off car). but if that does not work, goto any mechanic and get a fuel pressure test done, wont even cost 20 bux for the test. to take the throttle body off, goto the HOWTO section of jc

Too easy, thanks for the tip. I 've done this to my VP V6 so I guess the IAC will be similarly removed in the VS. Hopefully that'll solve the problem!
