.95 lambda at idle. That was hit with the Bosch injectors in for 1-2-3, Lucas in for 4-5-6 and the mixture screw at 5 turns out. Leaving that mixed injector combo in the engine danced in my head... Couldn't do it, even to just test mpg.
Just spoke with Bill (Mr. Injector) about the injector wideband readings. He leaned toward the situation NOT being injectors but did not take a bold stance on that. Mentioned I'd be sending him the Lucas to see where they are at. He said send the Bosch too and he'd recheck them under warranty. Your idea for swapping injectors is another fine idea. Is on the menu with a wrinkle...
I just sent the ECU to ProgRama in Boca to check it. When it comes back, either it is good as is or there was an issue with it... and Joseph fixed it. If there is a fix, I'll install it and of course wideband it immediately. If ECU checks out good without needing a fix, am swapping the injectors as you suggest.
Injector harness... running 12v through it tomorrow.
By the way, wideband... You played a large role in that happening here. Thank you for the repetition of advice in that regard. More, you're a supernova of all this air-fuel intel. So more thanks your way for raining it down on the arena I'm dancing in here.

The last place to send a questionable DME ECM for evaluation! Since scarceller has been very supportive in this thread, he should've been the 1st choice.
From what I've seen of the ProgRama "repairs" over 20 years, it shouldn't have been even considered.
Good Luck!
