the poor ECU. i wonder what it must be thinking as it loses more and more control over the engine.

how difficult would it be to retrofit a different IAC motor into our mani? what kinda flow does the IAC typically see? i would think if you were using a solenoid of some sort it wouldn't be that difficult to attach it to a vac line - effectively creating an electronically controlled vac-leak... which is really all an IAC is when you think about it... you wouldn't even hafta connect it to the intake - just slap a mini filter on the inlet to the solenoid. oh and a check valve for boost.

maybe i'm oversimplifying the problem though.
