1993 Subaru Cold Start Problem

[93WinterWonder]

My 1993 Legacy has had problems starting in the last month, January 2025. The weather is in the low 20s to 0 degrees. The battery is fully charged, and the starter motor works perfectly. The motor usually starts with a few rotations and the RPM bounces up to 2500 and then slowly adjust down to 500-800 range. Today it turned over for two minutes before starting and acted as if it was not getting fuel and then slowing adjusted to normal with the Engine Light On. Then when I drive the engine light goes out and everything is normal, though once the motor cools down it will again be difficult to start. The exhaust system and O2 sensor are new.

I have had this car for about eight years. It has been in the family for over 20 and has always been very dependable. Is there anyone who knows about this issue, with difficulty starting? Would it be vacuum or electrical problem? The 60 thousand was done and the motor is clean, and the car would not of had any major past mechanical issues, so it's got to be just one thing. What could it be?

Define full charged. Has it been load tested? Right battery for the car? What are the battery build date and install date?
