Hi everyone. I have a Jdm type r in my dc2.
When it's below -12 'C' My car idles fine and drives fine. But when I step on the gas "sometimes" it hesitates. Its the same on a cold start. And I do not let it warm up.
So before I was letting it warm up; but now it's so cold out that it always thinks it'd cold.
If has to be something with the air being so cold. Cuz over -10 it runs amazing.
Again; when I step on the gas it falls on it's face / hesitates and kicks power in spurts.
Also I have noticed my windows fog up a lot more.
I have researched a bit. And cannot find an answer.
Maybe thinking something to do with the themostat, or coolant sensors.
Maybe even throttle body sensors can't read the air cuz it's too cold.

Could use help on this.
Thanks.

 

it could be a coolant temp sensor or your coolant isnt warm enough flowing through the throttle body

 

Did your car do this? And what did you do to fix it? Or what should I switch out first.
Why would coolant too cold going threw the throttle body, which I didn't know it did. Make the car fall on it's face when you hit the gas.

The car goes into " choke mode " when you first start it. So when I start driving I think the ecu is getting mixed signals from a faulty sensor that is telling it to dump more fuel go heat it up. Even though the car is at perfect operating temperature: weirdest problem ever.

There's tones of posts on this topic. But no solid answers on what it is. Or how to fix it.
Just haunches. And they all seem to be replace the whole system almost, fuel, spark and all sensors lol. If anyone has had this problem before or herd of a solution plz let me know.
Thanks.
