Also, check for vacuum leaks...

Engine Control Input Signals
Water Temp
Intake Air Temp (AFM)
Oxygen Sensor
RPM Signal (Crankshaft position)
Throttle Signal (TPS)
Vehicle Speed
A/C Switch
Battery Signal
Intake Air Volume (AFM)

There are obviously others for transmission (gear selector, transfer case, etc.), braking (brake fluid level), oil pressure, parking brake switch, etc.
