wont hold constant revs

88 crx siR, p28/s300 ecu, b18c6, rc310's, obd1 dizzy, inj resistor box removed,plx wideband

the car wont hold constant revs above 2000rpm. with the throttle held constant the revs fall away to idle then return to 2000rpm. it seems fuel is being cut.

i have tried two different dizzies, same problem with both. wring has been traced back from dizzy to ecu and seems fine.

any ideas what my problem is?

You have no TPS reading. Check your TPS and the wiring for it.

problem solved - turned out to be a dodgy TPS sensor, many thanks :D
