dead spot @22-2500 rpm

I have a 98 f150 4.6 and at 2200-2500 it feels like someone pulls 2 plug wires off and it looses power. I have changed 02 sensors and plugs and wires and fuel filter could it be a bad injector? the truck has 150,000 miles on it. thanks for any info

I don't believe one injector would cause you to lose that much power at that RPM. I would be suspicious of a coil problem or losing a crank sensor signal .

Just a quick update... I replaced both coil packs this weekend( $103) from Autozone and all the problems disappeared. Thanks
