Figure 94. The old Idle Air Control (top of throttle body), was installed, along with the Throttle Position Sensor (bottom of throttle body), so that wiring can be done. They will be replaced with new units later.

Figure 95. The injectors and fuel rail were also re-installed so that wiring can be done. These will also be replaced later. The old injectors are 29lb units, and may be a little lean for running E85. We are looking at replacing them with 42lb units.

Figure 96. The stock retaining bolts for the fuel rail were replaced with black socket button head screws.
