Default Did a Compression Test

I changed my spark plugs tonight and I figured I would do a compression test just for kicks. I did not plan on doing one ahead of time so the motor was very cold (36' in my garage and the car wasn't started all day). The numbers came out very consistant but a bit low:

1- 212
2- 212
3- 214
4- 210

Are these about normal for that cold?

Looks ok to me man. If you had large differences between pistons I'd worry, but those are nice and close.

I think those #s are normal, because when the car is warmed up, compression #s will be a little higher. I also noticed, on my old f20c engine, and for you and others, that cylinder #4 had the lowest compression number, just barely tho.
