84 Z28 hesitating at 3/4 throttle!?

Hey, nice to see the page back!! i felt lonely with out it.. anyways, when i accelerate normally it seems fine, when i put it to the floor it seems fine, but around 3/4 throttle it hesitates... the plugs and wires are about 6 months old. the car also seems to loose power in the upper RMP range.. low end power is icredible, but it lays down when it gets up there. i don't remember it like this when i first got it a year ago..

thanx for any help you can give me..

Often overlooked things are a partially plugged fuel filter or a vacuum leak. I would look at the condition of the cap and rotor, and check the timing.

I think it's the fuel filter... my car did exactly that and my fuel filter was clogged. In 10 mins your car will be running fine again
