Tech Tip: Nissan’s Engine Idle Speed is 25 RPM too High
If you confirm the idle, in Park or Neutral, is more than 25 rpm above specification (with the engine warm), and/or DTC P0507 (ISC System) is stored, this incident may be the result of recent cleaning or replacement of the throttle body.

Tech Tip: Nissan Optical Distributor Test
Many Nissan vehicles have a power transistor controlling the coil (or igniter). The power transistor is a separate unit on optical distributors. It allows the signal sent from the ECU (low current) to activate the primary circuit in the ignition coil (higher current). This induces high voltage in the secondary windings of the coil, providing spark to the distributor cap and plugs. If this transistor is faulty, the necessary spark will not result.
