Unhappy Quick question here about my 86 n/a

so i was out driving minding my own business wasn't doing really much at all.. i come up to a stop light it was like 2AM and i haven't opened her up in a while so i don't launch it or anyhting, just take off slowly then punch her, well i get up to 3500 RPMS and my power just completly dies out.. i have a little bit and the rpms are still climbing but nothing is really there.. i let my foot off the pedal about half way and some of the power comes back but as soon as i go back on its gone.. and its sputtering and what not

i had a compression test done and its was 825+ on both rotors along with a tune up full service new plugs and wires

my question is.. could this be or is it secondairy injectors
or could it be 5/6th exhaust port accuators are stuck

i have full power at everything under 3500 RPMS.. anything above that over 1/2 thottle and i get nothing

ideas?

Search for "3800 rpm hesitation".

Oh, and sell me your engine if you have 825 psi.

******* have full power at everything under 3500 RPMS.. anything above that over 1/2 thottle and i get nothing**********8

I'd guess the secondary fuel injector plugs or just one secondary plug is OFF. They're easy to reach/see on a n/a 1986. Check it out. It's almost a given that is the problem.
