Having a weird stumbling (breaking up)

[turbotom]

Ok I finally got this 2g running after MIA for too long.

The car has:

stock 6 bolt swap
b16g
680cc, PTE injectors
3 inch turbo exhaust with high flow cat
fmic
ECMLink v3lite
ported 2g exhaust manifold
tial 38mm WG
2g MAS
AEM WB
etc....

The will idle lean at idle like 17.9AF, if I compensate it will get better but run super rich which in meaning no happy medium. Now when cruising, it stumbles, pops, farts and goes peg lean!!!if I add 40% - 60% it will go like a bastard but in WOT it does the same thing. After a run or 2, then it gets so bad you have to shut the car down, wait 10 seconds start the car again, and it's able to cruise some what and then repeat itself. I calibrated the wideband, TPS is adjusted, base timing is perfect, using BR7ES plugs, new wires, and new fuel filter. No matter what I did, nothing changes.


NEED HELP!!!! I miss driving this car but hate the way it runs.

I made a log but for the life of me, I have no clue how and it's driving me crazy,.

I changed transistor, resistor for injectors, CAS, MAS and IMP relay and still nothing. There is got to be something dumb that's causing this to happen, but what?

Update, well yesterday I set the DTCs to check off cylinder misfire. The car broke up badly thinking the CEL will turn on, wrong, nothing I update the DTC and no codes for misfire, I'm stumped!!

Here is my log trying to go above 4k:

Why do you have it locked in open loop? Remove the OL lock.

You need to add a few things to your log... CombinedFT, STFT, and LrndIdleAdj.

Then get an idle log of the car at operating temp (190*+), nothing else.

That's what it sounds like to me. What are your fuel trims at?
