Having SR Problems

[Mofuhcka]

SR is running weird, here is whats going on what I have already looked into:
Runs at 10.0 AFR
Replaced maf
TPS works
Coolant temp works
All spark plugs/packs are working
Injectors aren't leaking
O2 is replaced
No boost leaks
No old lines
Ecu is throwing code but won't let me read it
1500rpm idle

How did you test for boost leaks? When is it running 10.0 AFR? At idle, cruising, or under load?
Also, did this just recently start happening? Or is this a swap you just installed and are trouble shooting?

Idle and cruising. Under load goes lean. Sprayed all the couplers with starter fluid. When starter fluid goes in the system the idle drops

Do you have an adjustable fuel pressure regulator? Or if it's stock, have you tried another one? It's also worth opening the ECU to look for any burnt terminals or corrosion.

The FPR is working fine. Ill crack open the ecu

Try pressurizing the system and listening for air leaks

Try adjust iacv an make sure throttle closes aka throttle cable isn't stuck
