I'm losing my **** over this damn thing.
Been riding around with the laptop hooked up trying to get a log of this misfire. No misfires occur.
Drive to work today without the laptop hooked up, runs on 2 cylinders almost the entire way to work. Definitely bump/shock related, and i can't find anything that's loose.
If i can't figure it out by the time the MX6 is up, running, and broken in, i'm going to part the damn thing out. I could use the money for a viable winter beater anyways.

I didn't look at the one in the trunk, but i think i found the rest. I took pics, will upload in a few.
This Megasquirt has a breakout connector for wideband things.
I'm not having wideband problems, regardless.
Pics of what i found and my rage will follow after these messages from our sponsors.

Ok so. Random pictures, ramblings, rantings, and some stuff.
What is this?
Ground.
Ground.
Ground.

ECU Grounds v.WTF
I hate everybody. Cutting this out left a whopping 1/2" remaining at the plug to work with, so that was fun.
The only visible damage to the ECU. Brain and i have talked about this, and it's not likely to be a problem.
Anyways, i made sure all the grounds pictured were tight and solid, i zip tied the COP harness up away from flopping around on ****, and did something about that solder clusterfuck on the ECU grounds. No misfires yet, but who knows... this was intermittent anyways and would go weeks without doing it. I DID notice this morning that the tach wasn't budging at all going over bumps, so that's cautiously encouraging.
I logged idle last night, might post that up looking for pointers. Also saw something in my Accel Enrichment Wizard settings that i think might be causing the part throttle lean spikes. Will post screenshot when i get home to the computer.

Where do those ones on the timing cover go, then?
The 2002 i've been fighting VVT issues with had a ground or two on the timing cover from factory. That said, i don't know if the 95 would have had the same bullshit or not.
And how do i plug that thing into the power steering pump if the power steering pump is you know.... on the other side of the engine bay?

the 2002 is wrong too then.
that one looks to belong on the TB.
I mean its probably "ok" I guess, since the back of the timing cover bolts to the head, but that's not how it comes from the factory. from the factory all grounding points are to big items like head, tb, and block. not a timing cover bolt that goes through a bunch of plastic to a painted back plate that bolts to the head in 2 locations (under the cam gears)

The 2002 is 100% factory.
I'll have to dig around the TB on this car... i didn't see a spot where it went.
FWIW, that ground on the timing cover is connected to the ground on the intake manifold i showed in picture #2. Not that this is ideal, but it's not just grounding through the timing cover bolt.
Found this. I don't seem to have the thing that the ground are bolted to in this picture. Probably because VICS manifold?

you're welcome to think that, but its wrong.
but who cares, back to your car:
1st order of business: find a diagram of all the oem ground points. preferably some manual or something from mazduhh. re-do your grounds with non-crappy vatozone looking points with better (thicker?) wire and maybe a dab of solder?
I dunno, those grounds just look weak and misplaced and just janky. it will take all of 30 min to fix them and eliminate that variable

Been looking for a diagram of the ground points for a day or two now. No success, which is why i asked in this thread if anyone had one, i asked on GRM, and i asked on CR.
Surprisingly, CR was the only place i got anything remotely helpful. (How's THAT for a twist of fate?)
However, i don't know how useful that will really be for me, because of what the motor in this car is. I don't have the same points/brackets on the intake manifold for grounding.
The non-OEM grounds will take me about 5 minutes at most to replace with something better and is on the menu, but i'm not convinced that they're the cause of my intermittent bump/shocked problem that i may or may not have fixed last night but can't tell because it's ******* intermittent. While janky, they're all tight and making proper contact.
My main question is: Did i FIND all the grounds in the engine bay in this car? Whether we think they're weak or janky is secondary to my question right now. I want to make sure they're all accounted for before taking the next step.
