knock sensors:
20 N·m (15 lb ft).

Intake manifold:
• Tighten the bolts a first pass in sequence to 5 N·m (44 lb in).
• Tighten the bolts a final pass in sequence to 10 N·m (89 lb in).

EVAP purge solenoid: 10 N·m (89 lb in).

pound-feet (lb ft) is the exact same thing as foot-pounds (ft-lbs)

Not likely. Check the wiring.
