Aloha.
Firstly, yes I have combed the threads and found some similar issues but nothing exactly like this.
I have emailed with Edelbrock but its taking a week or longer to get a response to each email.

I need input from the more knowledgable of you here.
Car is an 06 GT.
Edelbrock eforce kit+CAI

Issues seems to be in the CL-fuel system but I'm not 100% sure.

Car will fire up, if there are no codes present it will sometimes idle fine and drive just fine.
Eventually it throws lean codes and the idle gets super rough and it can barely move under laod.

Fuel trims:
STFT
Bank 1 and 2 Range. -17 to +50
*when it decides to run well it showes STSF at 11-14

When it throws the codes I see all fuel trims zero'd out and my live data viewer shows CL then shows CL-error then switches to OL then back to CL

IAT is spot on around 143° (Hawaii)
Ign adv is between 5.5° and 11°
Fuel pressure at idle is 40 psi

The first motor blew a hole in the block, while swapping motors I installed 4 new O2 sensors from Bosche, checked all plugs and wiring, checked injectors and then replaced all of them anyway.
no leaks at exh manifold or downpipe connections.
Smoke check/leak down test, no leaks.

Any input would be greatly appreciated!

I’ve had an E-Force in my 05 since 2017.
Did you do the install?
What tune are you running?
What size injectors did you install?
NGK O2 sensors TEND to work better on our cars then Bosch.
Do you have a Boost-a-Pump?
The problem with the CL-OL points towards O2 sensors, or tune.
You also might check connections at the ECM for corrosion.
