I have a problem with my car when I start specially in the morning. The engine will start and then idle rough and my car is very shaky. Sometimes the engine will die after starting so I need to step up for gas. But after the temperature went up and I drove it for a few minutes, the engine is ok but stil with few vibrations at idle.

if the engine temperature sensor is faulty the ECM thinks the engine is the right temp buuut it is not and do not get enough petrol.
The other problem is if the ECU is stuck on closed loop and do not get into "cold enrichment" mode
