Question

I have installed new plugs. It is still sluggish in acceleration. I have added a fuel cleaner and injector cleaner. Sea Foam to be exact.
My next step is to check the ignition coils. Or new plug wires.
How to proceed for here??

Yes the ignition coil should be check, when it has a sluggish acceleration the ignition coil should be check for cracks, what happens on the top area of the ignition coil it tends to crack resulting in a lack of power at acceleration
