Hard Cold Start 2004 v40
I am baffled by a cold starting problem. The car is hard to start in the morning but a ok the rest of the day. Here is what has been done so far. The fuel pump has been replaced, the fuel pressure regulator has been replaced, the coolant temperature sensor and thermostat, as well as the idle air control valve has been replaced, I have taken it to three mechanics and they can't figure it out. I have cleaned the MAF sensor but have not replaced it. Where should I look next?
