I've a cold/ wet start issue. The idle either catches but it rough and low or will only idle if I depress the accelerator slightly. It normally sorts itself out after I've done a 15 minute drive, or go to move/ start the car later on. Just a morning thing it seems.
When it's being dodgy, I can find myself having to rev slightly at junctions to prevent a stall.

I'm thinking of replacing the spark plugs as a cheapish wonder of mine.
It's a VVC engine running ~175bhp. Used daily so has to preform in all temperatures.

Any recommendations for plugs or things to look at? Seems fine all summer long and it lives outside. Seems a winter issue when the temperatures go down and the cars wet every morning.

Could a bad battery affect this? I could test one day soon, but on the weekends when I have time, I tend to get up too late.

Right, I'm thinking that my battery - PV25 (?) is being affected by the parasitic load of my immobiliser and the cold dam mornings.

I'm thinking to fit a master kill switch and turn it to dead at nights which might help, if not, it'll add an extra level of security.
If no help, new bigger battery again, maybe the original banner.
