Thanks.

I was sick for a few years and finally got it sorted out for the most part, so fatigued that walking was a chore and had zero interest in the Jeep, but the fatigue is gone now. I had...

Will do....

The Jeep, '78...chassis in the garage is I believe an '85 Grand, I needed a centered rear D44 so I bought and parted out the Grand for the rolling chassis.

Noted, pictures attached...nothing fancy here, just a poor fk' trying to have fun with an old POS Jeep, thanks.

Noted, thanks.

Noted, thanks.

Telling me to stop working on the engine is not helpful, and that is exactly what you stated (grin)

That is too funny, grinning then, grinning now...

That is funny as hell, given that engines and transmissions are dyno tested before market, electrical harnesses, circuit boards are pre-tested, and in the construction sector, diesel engine...

Good question. To be honest I could stop now because I verified even though much was trial and error, there are no major mechanical issues, my initial re-flash was successful, the new rear main seal...

Thanks.

The 4L60 in sitting in my dining room waiting for the rebuild parts but that's for another thread or forum.

And while I am thinking about it, should the torque converter be installed...

What is the purpose for checking the voltages?

O2's reconnected, NGK TR-5 plugs and exhaust.

B1S1 connected and B2S1 disconnected ran engine for 1 minute then turned off. Voltages leaving B1S1 connected and B2S1 disconnected.

B1S1 connected - .000-.516 (climbed steadily for...

KOEO

B1S1 connected - .451-.464

B2S1 disconnected - .443-.451

B1S2 disconnected - .443.451 (no O2 sensor)

B2S2 disconnected - .443-.451 (no O2 sensor)

KOEO

B1 connected - .451-.456

B2 disconnected - .443-.447

2x, it's an unmodified factory harness and the O2's are plugged in correctly.

I don't think you are being harsh but you are showing your ass, I don't need a WB right now because I am not trying to tune a fk'n thing, it's a totally stock motor and I am trying to diagnose a...

And for grins I flashed the original tune with only VATS disabled to eliminate something I did turning off emissions and it still maxed LTFT's.

I ran multiple scans this evening, initially I swapped 4 and 6 coil and wires not thinking, both have the highest misfire counts. Then I ran it with the O2's disconnected and it was smoother for...

No WB yet, A few hours ago I ordered pipe to weld up a temporary exhaust, 2.5" with a transition to 3" and a 3" single in and out muffler I have in the garage/. It will be about 48" total from the...

Yes, both stubs are within a 1/2" in length frome side to side and O2's are both about 3" from the end of the pipe.

I did swap O2's from B1 to B2 and back again. LTFT issue is consistently on B2.

Hey guys, the computer lingo "garbage in garbage out" probably applies here so I will try to cover as much background as I can without typing a novel.

I have a 180K mile L59 pulled out of a Yukon...

This might be heard better ;)

Thanks for taking a look Jason.
