VS auto transmission car skipping

[Frog201]

hi i have a 95 VS commodore my car is missing (doesn't run well) when the car is in gear (eg D)
and you put the brakes on or if you let the brakes off and just rolls along.
The car runs well if your driving or it's in Park i think it's a transmission problem.
and i just replaced spark plugs and leads
please help


thanks

Maybe a bit more explanation is needed - like exactly what you mean by "skipping".
Also check for logged fault codes - it's easy:

From your description I'd say change the plugs and leads but you've done that already. A miss can be caused by many different problems but not usually by the transmission. Check the codes first as that might point you in the right direction.
