Take the car to any autoparts store for a free scan. See what the codes are.
If temp sensor is not working, it will run rich and cause a lot of driveability problems.
Have the scanner set to live data mode and see what PCM is reading as engine temp. If low 0 to -20, then the coolant temp switch is bad.
Do not confuse the coolant temp sender with the fan switch or the temp gauge sender.
