P2177 Idle Bank 1 System to Lean need help diagnosing Freeze Frame

I pulled a P2177 code. No other codes, car runs fine.
Cleaned the MAF, checked for evap leaks with starter fluid (none found), replaced air filter as the side seal was crimped (thought dirt may be getting passed it and fouling the MAF).

Cleared the codes and it came back in just a few miles.

Here is the freeze frame data...
ABSLT TPS% 25.9
RPM 2142
Baro Pressure 29.8
Calulated Engine Load % 55.3
MAF (lb/m) 2.53
MAP("HG) 24.5
Out Temp (F) 102
Coolant (F) 172
IAT (F) 104
IGN ADV 28.0
ST FTRM1(%) 23.4
Long Term Fuel Trim 20.3
Veh Speed 35
ABS Load 40.4
FUEL Sys 1 CLSD
Fuel Sys 2 N/A
REL TPS 16.5
Throt CMD 20.0
ABS TPS 25.9
Acc Pos D 15.7
Acc Pos E (no value here)
CAT TempII 1143
Egr CMD 53.7
Evap Purge 0.0
CMD EQ RAT 0.987
CLR DIST 12
CLR TRPS 0
Fuel Level 69.0
VPWR 13.677
End Run (m:s) 1:42

So, can anyone read the tea leaves and give me some advice on what is out of range and what that means?

Thanks
 
Forgive me for not knowing what evap leaks are....but I had the same issue and it was a tiny crack in one of my vacuum hoses. It took me a while to find it and the car always ran just fine. Just got the code randomly.
 
Checked for vacuum leaks and found none
Checked purge solenoid valve and it is good
Grounded the Throttle Body
Cleared codes and drove for a few minutes.

Code is pending. So, still have the issue.

I know these are out of spec
ST FTRM1(%) 23.4
Long Term Fuel Trim 20.3
Should be + or - 10.
What could cause this?

Anything else out of spec?

Also, step 5 of the Diag Procedure...
Access APP1, APP2, ECT, MAF, TP and VSS
PIDs using M-MDS.

What are these? and what should the values be?
 
I read a dirty fuel filter of faulty fuel pump can trigger the p2177 code, has the original fuel filter ever been changed?
 
Well the good news is I don't have to worry about the code anymore.
Bad news is that it is probably totaled...

Someone did an illegal u-turn directly into the path of the car. No one hurt.
