Hello, this winter I found myself having trouble starting my Renault Clio in the cold, but it only happens if I let it sit overnight in the cold, It has no problems starting with a cold engine if it doesn't sit for very long. It feels like it's not getting enough gas because to start it I give it a lot of gas and it starts, but I can't let go of it until it revs up higher by itself (not moving the gas pedal) or it will stall, but meanwhile it makes a crap ton of smoke. What do you think it could be?

smoke is either head gasket leaking or injectors flooding out the engine. I would assume injectors need serious cleaning or replacement
