ECUtalk Readings --What's wrong?

[ReLiC]

I've been having problems with this motor for a while and haven't figured out the problem. I hooked up my consult thinking the problem would be obvious but i can't figure it out, so any help is appreciated.

It's a Type x s13 sr20 in my 96 240. It had 1 fault code (knock sensor) which i bypassed with a 1M ohm resistor. Now that code doesn't show up so i think that's fine for now (will buy sensor later).

The problems i'm having:
-Slight misfire
- Idle is unsteady

I took 4 screenshots on ECUTALK once it warmed up. I noticed that idle would be at around 1k when everything seemed fine. All of a sudden the car hesitates, the "ALPHA" gauge would drop from 100 to 70 then the idle would rise to 1400, then the O2 gauge would raise from .55 to 1.55. Then everything goes back to normal ( 1k rpm, .55 o2, 100 alpha) and after another 20 seconds the whole things repeats.

I believe this is normal condition, the idle is a bit high but the rest seems normal:



Right here Alpha has dropped while the RPMs are increasing


At this point RPM is high, Alpha has gone back to 100 already and the O2 is reading 1.53
