cylinders 2 and 4 running rich :confused:
So I'd been wondering why in the hell my car was cruising/idling/everything pig rich (like 11.5 and richer CONSTANTLY) and thought I'd change my plugs. This is what came out, cyl 1 on left, 4 on right:
So, judging by those, I don't think it's my tune...
Here's two logs, just driving normally to and from work:

I should mention the car idles like a Subaru and bucks a lot during cruise, definitely NOT smooth anymore. I remember the cylinders are batch-fired and was wondering if that might have anything to do with it.

I'd assume you are getting spark on all 4 since its running super as nasty rich on 2 and 3 and the way its batched....
so either you have 2 dead injectors, or two leaky injectors, or im completely wrong.

Leaky injectors would be a good explanation, but the fault in it is that it might not be that likely that both 2 and 4 started leaking simultaneously.
I just got the taillight too man, thanks!

Here's the .msq \/
Abe: That's what I was thinking might possibly be the problem, but didn't want to jump to that conclusion lest it be something more simple.
It always does it, I can't remember when it started but it hasn't let up since I first noticed it happening. It's like clockwork; after startup, AFRs will be around 15:1, then climb to 17:1ish, then drop steadily to 11.5ish, sometimes 10:1 in cruise. Just measured my MPG - 16 MPG...

your ego settings and AFR table are screwy.
RPM Based ACCEL needs to be off.
ASE table should go to 0% at 160*
timing and fuel tables at idle look crazy low.
overboost is at -5.7psi, might screw things up.
