I got a DF115A and the computer shorted out. Replaced computer and engine will now start but won't idle. Checked IAC valve and showed short to ground. So I just replaced The IAC valve and still will not idle. anyone out there had the same problem and have a answer for what problem I have. it also doesn't have any trouble codes.

The bad IAC was likely the reason why the ECU was originally damaged.
Did a dealer do the ecu replacement, or someone else? Because they should have replaced the IAC at the same time. There was I understand a service bulletin issued to dealers re this exact issue.
I hope that the new ecu hasnt already been damaged already by the faulty IAC.....
There have been a very, very small number of similar cases, a friend of mine was the first case in Australia when this happened 18 months or so ago.
