You are right, if the timing chain were bad it would have the problem all the time , not just cold . This to me sounds like a coolant temp sensor . Hooking up a scan tool that can view engine sensor data , i would check the sensor parameters . most noteably the coolant temp an IAT - intake air temp. after sitting over night these should be very close.

Hopefully, you didn't drive it any of those three days that it didn't have oil in it. If you did, chances are very good that you damaged the engine. You say the car is shaking - do you mean the engine is shaking when you're sitting still? Is it also making strange noises - knocks, clunks, squeaks/squeals? Then you almost certainly have damaged the engine. Putting oil in the engine does not heal the damage that is already there. Expect that your engine is going to seize or just quit running soon.
