The car has been doing this for some time and ive been using the search button to help me out. It stumbles/looses power under 4K. Doesnt matter if is cold or warm. To try and fix this problem ive replaced the following parts:

New OEM fuel filter
New NGK spark plugs gapped to .044
New OEM cap & rotor
New OEM timing belt, (old one was loose and stretched)
New water pump
New thermostat
Double checked my static timing and ignition timing, (distributor is positioned in the middle)
Also did a complete coolant flush with honda coolant
Fresh valve lash on sunday

I hope someone can help me out. Ive been going back and forth wondering if it might be a HG issue. Any input wld be great, thx in advance.

Any codes? Could be the ignition coil, or could be fuel related like the main relay or the pump it'self, or just the ECU.
