motor sound

when i get going around 40-45 and it downshifts to around 1500 rpm the motor seems to change sounds almost like its struggling to run and the wheel and petal shakes but when you give it more fuel it goes away when the rpms move up over around 1700 rpm it runs better... the injectors were changed 1000 miles ago because of this problem and it went away now its back.. my fuel sending unit isn't working and was going to change it.. could it not be getting good fuel pressure? i have no way to check it... and if the sending unit is clogged could it hurt the injectors with bad fuel pressure?

would running with low fuel pressure ruin the injectors or is it only if you run them dry?
