Thanks. I've downloaded the powertrain diagnostics PDF from mistubishilinks.com, and I also have a Haynes manual which has a list of possible causes for the erratic idle of the second ecu.

The driveability pdf is for the '87. How much of that is applicable to the '90?

I'm working through the checklists, but wanted to know if there was anything obvious to someone familiar with the vehicle that might be happening.

Thanks.
