Time for the compression check. Kept the TH at WOT and disabled the INJ by disconnecting the connector to the INJ resistor unit. Later models have different INJ spec so there is no INJ resistor unit and just a simple connector with metal bar inside to create short circuit. In the process of compression check. ...

On early model NSX, when TB is under tension, you may find ...
