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

stock ecu? why are you not running vac to the fpr, and also why no 02?

PRC K20A. The guy that sold my buddy the ecu said to set the fuel pressure there and leave it off. Thats how he had his ran. (I told him it needed vac). It has no O2 cause the exhaust shop was out of bungs. Should have it in friday

no o2 sends it to limp mode, horrible fuel curve and verry little power. your fuel pressure should be at 49 or so, stock. unless it is a kpro ecu, he is way off.

49 psi with vacuam or without.

with vacuum.
