For those who have done the CFI to MPI conversion you will no doubt run into the problem of the car not idling because the Idle Speed Control circuit is slightly different on an MPI.
Here is how to fix that.
1. On the old plug that the CFI Idle motor plugged into (it has 4 wires, see pic) cut the Grey/White (with red bands) wire.
2. Extend the wire by about 2 to 3 inches.
3. Wire the extended wire into the engine loom side of the Injector Loom Plug in the hole as shown in the next pic.
This hole should corrospond with the thicker Grey/White wire on the Injector Loom side of the plug
Reconnect the plug and start your car!
