ok, i've spent a lot of time reading about poor idles, bad idles, slight loss of power, bad mpg, etc.

i've done a ton of things to try to fix the problem, but i'm at a standstill and wits end.

here's my story:
91 ka24de. 94k mi. car ran alright.(i didn't say great) felt like slight power loss at low rpms. slight hesistation before 3k, fuel cut occured sometimes at 6krpm instead of 7k, poor gas mileage (15ish). throwing code 34. idle sometimes bogged between 700-500 randomly at idle. feels like it's misfiring at idle. did the double exhaust cam trick a week ago, now it's very apparent it misfires at idle. shakes.

replaced ects, knock sensor, ks wiring subharness, engine harness, did 1M resister trick...no luck. still throws the code motor mounts are good, replaced ecu. still same code. swapped mafs, no luck. even tried running 91.

the cabin wiring is kinda screwy on the car. when i brake, the rear defrost light comes on, dr front side speaker doesn't work, yet i get continuity. sometimes the seatbelt light comes on randomly.

if i can't fix it, i'm gunna think about either selling it or making it into an ITA spec car and run se-r cup.
