Default Lagging acceleration at higher gears?

I have a 92 ES300 5 Speed and just replaced the plugs and plenum gasket since I was getting some rough idle etc. Still when I am in 4th or 5th gears i get no strong acceleration and lagging throttle response or very rough staggered response???

Downshift to a lower gear for better acceleration. How long have you been driving a manual vehicle?

My powerband is weakest in 4th or 5th too. 5th is just for cruising. You can advance the timing a few* to help it spool up quicker. How are the knock sensors doin? You replaced the old plenum gasket with a new one like a good boy right?

Knock sensors are mounted to the block in the valley between the 2 heads.
