Vehicle shutters and hesitates at cold starts in mild degree weather

My vehicle for the first time since I replaced the leaking old thirty year old clogged fuel injectors is still shuttering and hesitating at cold starts at 60 degrees or higher weather. When it’s frigid it starts with no hesitation at all. After it shutters on me it feels like the engine wants to shut off on me but the computer regulates the idle after a couple of seconds and smooths it out.

I did research and think it may be the coolant temperature sensor because the coolant temperature sensor sometime doesn’t pull a engine code when the sensor is bad. It also regulates fuel and air mixtures in the airs atmosphere if the car is running lean. It can also smell like unburned fuel at cold starts which I am smelling. After I drive to engine temperature it’s back to normal. I didn’t let the engine warm at operating temperature because I had to clean the garage out to move the car out of the drive. I just parked it around the corner and shut car off. Came back later to bring it back and it did it the second time.

Here’s what I replaced all last year:

- Spark plugs and spark plug wires. I did notice one of the spark plug wires have a small hole in one.
- Idle Air Control Valve
- Coil Packs and ICM
- TPS Sensor
- Map Sensor
- Fuel Filter
- Fuel Pressure Regulator
- Fuel Injectors and o ring seals
- Air filter is still good too and throttle body bore is clean

Before buying a coolant temperature sensor should I reset the Idle air control valve do the relearn and drive it?
