Forrest,

The faults codes (called Diagnostic Trouble Codes; DTC) are contained in menu #5. These codes are stored in the DIAG MODULE (N59).

Since you weren't able to 'decipher' the page, here they are:

9 ---Intake Air Temperature sensor (IAT), open/short
18 --Adjustable camshaft timing solenoid, open/short circuit
26 --Upshift delay 1 to 2 (model 123.034) , 2 to 3 (all models)

They all 'point' to the LH-SFI module and need to test it. But, of course, it could be;
"9" -- a loose or bad IAT. It's located in the left side (drivers side) on the air intake hose.
"18" -- a bad camshaft solenoid; located on the header (each side)
"26" -- probably a bad vacuum line.

Hope this helps you.
