After redoing my water pump, and throwing the opti on, my opti was wet so i couldn't go over 1/4 throttle. its cleared up now, and runs perfect in open loop, but once it hits 180 i guess it hits closed and if i give it any gas below 2k rpm it won't go anywhere.

also, the vacuum check valve near my PCM is broken and duct taped, but i don't think that has anything to do with it.

also -- the car runs at 20psi oil pressure when it heats up below 2k rpm, at 2k it jumps to 30 and full throttle its at about 38.

is that bad pressure? it seems to degrade after 1000 miles driven.

i'm doing a turbo build soon so its going to be all redone anyway, i just figured i'd see if theres anyway to fix it for cheap.

 

Does feel like its stumbling under 2000rpm? What happens when you punch it?

Your oil pressure seems a tat low, but i dont think that would make your motor run like that. If when you punch it under 2K, and hit hesitates really fast and then takes off like normal, sometimes that can be a egr value.

Also maybe your 02 Sensors are going bad

 

i'm thinkin o2's are bad since its closed loop only.

oh yeah, the pressure has nothin to do with it, i was just concerned because its so low.

under 2k rpm it sounds like its flooding itself, doesnt go ANYWHERE unless its under like 1/4 throttle, then it feels like its pulling

 

o2 sensors prolly bad.
