i have a vr 5 speed it idles real low n stals heps on me even when im crusin it will just loose revs n stals up and it chews heaps of fuel runs real dodgy to mayby droppin a cylinder is that coil pack related ??
n it has really sluggish exhaleration to ?? engine light comes on heaps to n when i have the aircon on it sucks heaps out of the motor like u can feel it loose power when i turn it on

Stuffed leads,plugs,oxygen sensors,dirty injectors? just a cple of possible causes.
oxygen sensors would make it run a bit rough and use extra fuel,should be changed around every 100,000klms.

i just changed the leads n plugs i was told about the ox sensore ill do that anyway but i noticed a hole in the exhaust to would cause major issues klike that ??

nah a leaky exhaust would just make you loose a bit of power and be noisy,wouldnt cause it to stall and idle rough.

First thing I'd do is check for any error codes.https://forums.justcommodores.com.au/threads/checking-error-codes-vr-vs-revised.22307 Dead oxygen sensors will make it use more fuel,but won't make it stall or run like crap.They aren't even used until the engine is up to operating temp.

Coolant temp sensor may also be stuffed - this tell the ECU that the engine is warm/hot and to vary the amount of fuel the injectors squirt in. Also possible the catalytic converter is starting to block....or maybe the exhaust has a kink in it from rocks/boulders.
