I live in michigan where today it was 20 degrees this morning, i started my car to go to school and it doesn’t want to stay running ( i have to feather the gas). i eventually just drove holding the break and driving with my foot on the gas at all times, does anyone know what this could be? I just replaced the battery yesterday and the problem wasn’t occurring before.

I had a 1996 Mustang GT that was completely un-driveable after a battery disconnect. The idle re-learn procedure had to be done to just get it down the driveway after any repair.
Back to the basics. Check for blown fuses. Especially fuse F2.2 and F2.8 in the Central Junction Box (CJB 1999-2004 MY). Confirm key on power using a known good ground. 1999-2004 MY fuse panel schedule...
This is why it's so important to maintain the battery and charging system in tip top shape.
To anyone else reading any of my posts I usually include the line: Today's cars simply will not run right without a strong battery and charging system! Cut corners here at your own risk I'm a big believer in starting with the basics. As such I...
I would let my car warm up almost all the way if it were me. Even here in florida when it gets 48 I let it get plenty warm. My Tacoma hardy goes until its warrm. Its got 350,000 miles. Some articles say its bad or not needed . Always runs better in closed loop.
