Hows the timing?, Did you check the plugs to see if its running rich? What MAF are you using?

its SD, it does feel a slight power loss but not logg "boggin" i took it to a shop and they charged me 60 to set the timing.. the problem still occured a little bit.. so i think i need them to restab the dizzi.. because i think i might of done it wrong.. when i dropped it the rotor wasnt pointing straight back.. it was slanted slightly.. do u think that can be it??

Sure you're not hitting the factory rev limiter? It shuts off fuel to alternating cylinders and feels like a mondo miss. It's only at 6200 RPM and it would be easy for your tach to be off.

Yea,had that happen befor,pull all your plugs and check them,see if any are fouled.If not,put them back in and push the wires on tight.

If its running fine everywhere else in the rpm band Its not your dist. Check all plug wires with a meter, or if they are old replace them, with a new cap and rotor, and auto light spark plugs. If that does does not cure the problem, If you still have the stock coil, replace that with a msd or accel. That should cure you high rpm miss.
