Default Paper clip diagnostics questions 1990 base auto

I am chasing a 8-900 rpm idle in park. checked vacuum leaks. My paper clip diag begins with C12 so its working but then sections are divided into 1.0 1.1 1.3 1.4 which doesn't seem to correlate with the FSM. Getting codes in 1.2 like 100, 44, 11.8 11.2 94 85 which don't seem right? Only code that hits is 58 dealing with trans fluid?

What am I doing wrong? 90 base auto. My dash temp gauge reads low but that doesn't affect the ECM?
