SR20DET rpm dips when applying throttle

Did you do a full resistance sweep of the tps? Could have a dead spot.

Ye i did. It goes smoothly from 0.45v to 4.2 or something. No dead spots

Edit: i also read a bit of the FSM today and they covered hesitation part. Said to disconnect your FPR vacuum hose and see if it still hesitates. And to pinch the hose that goes to the pcv and see if that fixes the problem

Are you sure its oil on the plugs and not a layer of wet fuel on a carbon fouled plug? I found the same things, but i think the plugs might have fuel on em. Found this too:

I tried the fpr hose and pcv hose things, no change there for me though. Interested to see what you find.

s14rebuild is talking about testing the resistance, not necessarily the voltage sweep. Mine was sweeping voltage eh alright but was really f'd on a resistance test. Vid of the testing:

Changing the tps didnt resolve the issue on my end. Coil packs tested to spec @ 1ohm

OP: is your o2 feedback idle control turned on in your commander? When was the last time you replaced manifold injector oring seat things?
