It really doesn't. But thank you, none the less.

Thank you. I'm doing my best.

Thanks. I called SouthBay Fuel Injector (in Long Island, NY) and they sent me a set of refurbished and flow-matched 30lb injectors for $29 each. They arrived ~50 hours after I ordered them.
Which brings me to today's post.
Kelly texted me yesterday just after lunch that USPS had delivered my new injectors. The ECU, now equipped with upgraded injector drivers, was sitting by the stairs. It looked like everything was coming up roses.
1700 came and I left work. I got home ~45 minutes later, changed clothes, gave Kelly a smooch, and headed down to the garage.
**Jump-cut to mini flashback**
Sunday on the test drive of Mike's Jeep, something rattled off the truck and jingled down the road. I didn't see anything and figured it was a screw/bolt/nut/unimportant bit.
**jump-cut back to story**
I open the drawer that contains my allen keys and all my wrenches.
"Where the fork are my allen keys?"
*finds 4mm and remembers last time they were used was to attempt to tighten the mirror on Mike's Jeep.*
"Son of a bush. Honey! I'm going for a quick bike ride. Back in a few minutes!"
*Airs up tires on MTB and pedals down the road to where the jingling occured just a few days prior.*
*Finds allen keys on side of road...missing two...one on bench at home...looks more closely at side of road, miraculously finds other allen key.*
I jam them all in a pocket and return home feeling that maybe the universe was back on my side.
Once home, I removed the two screws that secure the fuel rail above 4-6. A gentle nudge and I'm awash in 93 octane. :facepalm: I clean up what fuel I can and swap the injectors.
Wash, rinse, repeat for 1-3.
Flashlight and fire extinguisher at the ready, I primed the fuel system to check for leaks.
No leaks, so I primed it again to make sure there were no bubbles and things would go smoothly.
Still no leaks.
Push the car out into the drive (so it can burn without burning down the house) and jump in.
It fired right up. No leaks, no drama. It actually fired up easier than it has in weeks.
I hooked up TunerStudio to take a look at my numbers.
PIG RICH
Don't care. It's not popping or doing anything weird, so I set off on a drive. It runs rich the whole time, but it runs strong. NBD, I can re-scale the VE map to account for what difference there is in the injectors.
If I stopped the story here, it's a success story. Alas, my automotive sagas are Sisyphean more than they aren't.
I went in and had dinner with Kelly and then back out to see what I could do about the ultra-rich VE map. (I was cruising at ~11.0 AFR)
Car still warm, back out onto the road. The VE map seemed pretty a-ok above 16% throttle, so I leaned it out below that.
It started popping and stumbling again after about 90 seconds.
WHAT
THE
FORK
It's getting dark by this time and I'm 10? 20? miles from home on a 2-lane country road I absolutely don't want to break down on. So I stop again, fatten it back up and head home. It's happier, but still just dumping fuel into the cylinders. As I drive, I'm trying to wrap my brain around what I've missed. I've got spark. It pulls like a freight train at high throttle input. Pulls hard all the way to 7k. It's not a spark problem.
I've clearly no shortage of fuel. Were the fuel pump failing, it'd go way lean up top, not when I crack the throttle or just tip-in.
The ITBs are most sensitive at minimal throttle input. That's where I'm having trouble.
***I remember at this point that I'd raised the idle ~200rpm right before this whole thing went to poop.
"I bet those GD throttles are out of sync."
When I got home, I pulled it into the garage. It's full dark in late May, so I knew it was late. Still idling, I prop open the decklid, grab the sync-tool from the tool chest, and unceremoniously remove the 1-3 rain hat.
#1 - 3.75
#2 - 4.25
#3 - 5.25
"MFer"
I shut it down, closed the garage, and went inside. Too late to be messing with that loud car or I'll never hear the end of it from my forking neighbors. Have I mentioned that I hate living near people? Society and civility are scams. I digress.
When I get home tonight, I will re-sync the ITBs and see if that fixes the problem I've spent too much time and too much money to fix. I suspect it will. That's often what happens to me. I throw a bunch of money at a problem whilst mashing my head into a wall only to find out later the real fix was nearly free and would have been right in front of me if I had another set of eyes on the problem.
Ever been so tired of fighting your car you consider a plastic 964 manifold with one TB and exorbitantly expensive EFI just to ensure the thing runs right? Because I'm right there, right now. I hate the sh!+ out of my car right now and there is little to be done about it except fix it.
