[V8] Who Works on ECUs?

[Carol, Dave, and Zach Weiss]

Looks like the intermittent high idle problem is the computer-new idle
stabilizer and speed sensor, rung out all the wiring from the computer to
the sensors, and it's still throwing the speed sensor code (and only that
code).  It seems the computer clamps the idle when it loses the speed sensor
input; otherwise, it should be reporting idle stabilization out of range.
An ECU from an automatic has no codes, and the car runs normally with it
(although at a slightly higher idle than a 5-speed would).

 

I have Ned's chip, but IA seems to be more into turbos these days.  Is there
anybody that repairs ECUs, or should I try to get Ned himself involved?
