Some where around 10F degrees my car will not start in the morning. (last year)
Plenty of cranking power. Replaced battery. If I plug it in to the OEM heater over night no issues.
I replaced my coolant temp gauge, and I was going to replace my air temperature sensor.
However what I thought was my air temperature sensor is really the air charge sensor. Sounds like some thing that more monitors the air flow?
Am I right to replace the air temperature and leave the Air charge alone? Is the sensor some place near the radiator?

Its on my 98 Taurus Wagon DOHC

Dont throw parts at it. Use a scan tool that will monitor PIDs like ACT/IAT, ECT, crank RPM (to see if the CKP is talking to the PCM) etc and see what the sensors are telling the PCM.
