engine runs like s**t

car stumbles, misfires, doesnt respond to throttle until a couple seconds after the throttle has been let go, and over all isnt very driveable

ecu throws code 33 (o2 sensor)
sensor is new, replaced it thursday under warranty
fuel pump is new
injectors have been swapped a million times, resistence between 12 and 12.8-9
no vacuum leaks
harness is fine

wtf could it be?

also throwing code 34 (knock sensor), could that code make the car run like shit? im pretty sure its a faulty sensor or subharness and ive been throwing this code for a while so i dont think its the major issue but i dunno how important it is

new parts include plugs, wires, cts, from auto to manual tps, changed the ecu cause the old one had 3 burnt chips, new cap and rotor, tried a different coil for the fuck of it
motor has great compression
cyl 1-185
cyl 2- 184
cyl3-4- 190
 
MAF reads perfect per the FSM's specifications
Also checked dizzy, all 4 injectors click in firing order and it fluctuates from 0v to 5v like the FSM says its supposed to, still stuck as fuck as to what the issue could be
 
knock sensor code will cause the ecu to constantly retard timing and make car feel slow

just because a part passes the resistance check does not mean it is good a resistance check is just a diagnostic aid not a guarnteed know all check i have seen many bad maf sensors that ohmed out ok
