Hello,

I am living in Norway and just now the temperature is about 5-7 degrees

below zero. When the sun is shining directly on my 300ZX TT, the car is

always hesitating/stumbling when the car is cold! If the sun not are shining

the car behave just normal! I got code 42 (fuel temp sensor) when I run the

ECU diagnostic, but I have just replaced the sensor. May the sun affect any

other sensor so that the car is "fooled" to think it's warmer than it really

is??

 

 

Thanks-

Egil

You might have a bad connection on the temp sensor, give it a good clean and see if that helps.

 

In fact give all your connections a good clean while your under he bonnet.
