Heres the setup
95 ex coupe
K24
no O2 sensor
no vac on FPR(60psi)

idles fine but going down the road at part throttle it is very sluggish and its like it stumbles
at WOT it feels like its not all there. Then at 5000 rpm it almost goes to sleep. At 6500 vtec kicks in and it runs like a scalded dog.

Anybody think it has to do with the fuel pressure(60 psi) and/or lack of vacuam, or the O2 sensor not bein connected

any help would be much appreciated
