The compression test is good, all cylinder is ok. my possibility is on the throttle body and idle readjustment, or ECU, or TDC, but I don't no how test this item.

How does the coolant look, does it miss a little when you first get it running. I am gonna bet you have a possible bad head gasket.

You may want to switch to a different oil thickness... there are some made to help start engines in cold weather.
