Now did you switch to 2 wire O2 sensor? if so did you change the factory wiring harness?
I believe the knock sensor was not changed after EGR was removed but could be wrong.

Yes you have to wire the new knock sensor if you have a single wire one but dont worrie is very easy to do, here is how to : on the one wire sensor you have the sensor wire connected to pin number C1-33 that wire needs to be put now on to pin C1-34 because on the 00 ecu the C1-33 its not used anymore so.... now for the other wire on the 00 knock sensor you have to run a wire from C1-32 on the ecu to the gray wire on the knock sensor.
99 pinout With EGR
C1-32 Ks reference low ( with out EGR ) gray wire.
C1-33 Ks signal ( with egr ) drk blue wire.
C1-34 Ks signal ( with out Egr ) drk blue wire.
00 pinout with out EGR.
C1-32 Ks reference low...... gray wire from the knock sensor
C1-33 Not used.......
C1-34 ks signal...... drk blue wire fron the knock sensor
As for the 02 sensor i have a heated sensor i already had put in my car so i havent messed with that part yet but here are the pinouts for it... its the same for the 99 and the 00
C2-21 O2 sensor 1 low ( tan wire )
C2-22 O2 sensor signal ( purple wire )
C2-23 HO2 sensor 2 low ( tan/white )
C2-24 HO2 sensor 2 signal ( purple/white )
well theres all the info hope this helps you out..
