Fiesta 98 ​​Failure in low when starting

Good evening everyone in the forum, I hope you can help me, I have a 98 Endura E 1.3 engine and when it starts in the mornings it trembles a lot because the engine does not remain accelerated, I have to accelerate it for a few minutes to take its normal rhythm and no longer gives problem. But cold start is supposed to be controlled by the computer without the need for me to accelerate it. My question is whether the computer will be bad or maybe it is some sensor that is dirty or damaged, if someone has an idea of ​​what causes the failure or had it in your car please give me how I can solve it, I wait for your answer and thanks for your support, they have a good day

Friend is usually cold starting problems is the product of a malfunction in the motor refrigerant temperature sensor, or the oxygen sensor, but something special also happens with the coils and captors of crankshaft position but these would basically be the factors of a herratic cold game.

I would first verify the temperature sensor

after you can look at the Realnti actuator that would be the step by step this can be locked since 98 the car may have the original and is damaged.

Check the wiring and look if they took the thermostat in the heat of heat and now in winter it will need it because the engine needs heat!

Good luck friend!
