Should the R.P.M. decrease when my foot is off the accelerator of my 1999 VT Commodore Sedan? What is the R.P.M. supposed to be when idiling?

SOURCE: Vt Holden Commodore stereo wiring diagram

head down to your local auto store and you will be able to pick up a wiring harness adaptor. you wire your stereo to this adaptor then you simply plug it into the wiring loom. no damage to the loom so if you ever need to reinstall the standard stereo its just an unplug and plug back in. its extremely simple and colour coded so there are no mistakes.

SOURCE: commadore vt key will not turn ignition on

providing you have the chipped key in then its possible just like the old days but iam wary on giving this information out ,do you mean the key will not turn if so then the steering lock will not release except a VW ,or does key turn and nothing happens

SOURCE: can you tell me what the symbol on dash is 'far left' please? vt holden commodore 1999

I am not familiar with your vehicle, Ive never heard of it. However a lightning bolt symbol would probably indicate a problem with your electrical system, possibly the battery or alternator.

SOURCE: we have a 1999 commodore vt sedan an we just put new battery an alternator in it last week an the battery light just came on an now it wont go offcan anyone help please

The battery is charged by the alternator which has computer (PCM)controlled voltage regulation, this makes for a much more precise engine and stable voltage for the engine management system.
