Help! KA24DE wont pass over 4000 rpm

I had only 3 injectors about a month, and yesterday i bought one to fix it, i installed it and all 4 cylinders worked perfectly, except for one reason... every time i tried to step on it, it wouldn't pass over 4000 rpm.. sometimes it would but it would struggle a lot so it was like 5k rpm then pushing me backwards and forward and not doing good acceleration... I think it was like 11 sec to get to 60 mph.. anyone knows what could be wrong?

Check your spark plugs. Bad injectors foul plugs really quick, then check your dizzy, cap and rotors, your spark plug wires, then your maf and air filter
