1992 Daihatsu Charade

Engine Performance problem
1992 Daihatsu Charade 4 cyl Front Wheel Drive Manual 230000 miles

Request information on where to buy a fuel injector puller for this car.
I will replace all injectors. Is there a brand that I should purchase, Bosch etc?
The car has a miss at idle, low RPM and at hwy RPM.
Give more throttle when miss happens, miss is softened.
Changed out the dist. Cap, rotor, wires and spark plugs, these were needed. # 2 cyl, is leaner than other cyl.
Other tests?
I am a Coast Guard electrician, Retired.
Thank you for your time,
PS. How do I donate.

You do not need a special tool to replace the injectors. OEM parts are best
