And I circled the EVAP purge valve. It's in a different place on 2.2 & 2.4.

 

Thank you for the pic!!
yeah, I unplugged the blue connector to it last night when I was working on it to move it outta way (so I won’t damage accidentally.) and it was left unplugged! Totally my fault.

now I can focus back on P0101.

Thank you again!

 

Update:

i havent seen P0101 come back.
I like not to see the CEL but at the same time, I really want to know/ understand why it came on in the first place everyday for about a week and all of the sudden it’s gone.

I ordered “Blue Driver” (Bluetooth OBD2 scanner) so I can monitor my car from now on if/when any issue come up.

 

P0101 is a type B DTC,
Conditions for Clearing the MIL/DTC - Type A or Type B
• The control module turns OFF the MIL after 4 consecutive ignition cycles that the diagnostic runs and does not fail.

• A current DTC, Last Test Failed, clears when the diagnostic runs and passes.

• A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic.

• Clear the MIL and the DTC with a scan tool.

 

Or the famous battery lobotomy!

 

just as I expected:
now that I have an OBD2 scanner, ECU has been behaving. No code (p0101), no CEL. Car has been running great.

Whats still puzzling me is that I don’t know what fixed the issue....
but since it’s running good now, I don’t worry about anything and just enjoy my new-to-me 2008 SS.

I LOVE this car and enjoying every second of driving it!

I hope I didn’t jinx myself... lol

I really thank you all of you who gave me suggestions/ input on issues I was experiencing!

 

Ours is not to reason why, these things just happen. Enjoy that SS
