Timing belt problem

Ok so just recently I replaced all 4 fuel injectors on my car ( stock ka twin cam) and now the car is running sluggish, it idles low when on netural and when I floor the pedal in gear it takes a second or two to actually start picking up speed. I think it's the timing that might be cause the problem but i am not sure any ideas?
Also when I step on the throtle and keep it the exhaust pops like it's misfiring
please help guys

KA have timing chains...

you should really check your spark plugs, wires, dist cap, and rotor first.

low idle can cause by dirty or clogged IACV.

Why ask if you're going to debunk the suggestions?

Check timing, fuel, spark, and air. There's nothing else required for the engine to run.
