Mine had just been disconnected for almost 3 months and it fired straight up.
So that's true even if it's been sitting for months? I wasn't aware of that. I was told the computer would lose ALL memory and the car wouldn't start, so that's refreshing to know.

I have always left unused cars with the battery disconnected, but for the above reason I kept this one on the charger.

So 3000 rpm for 15 secs gets it thinking, and then a short drive will reset the computer's parameters? This is an LS1, not the Holden V8. That's what you've got too isn't it?

Thanks everyone else for your advice, Saturday will see another thorough cleaning.
