This a DJ code ECU, harness, and all systems as they were in the donor vehicle. So no O2 to worry about or wiring mishaps, as things were fine for several years until winter. 

Thanks for bringing up the Temp 2 sensor - I will test that!

Chris.

> Most likely you have a bad idle valve controller. There are a number of outside factors that can cause this. Temp 2 sensor goes to the ICU and if a 2.1 system was added to a 1.9 ECU may be part of the problem. A bad ground for the temp 2 sensor can also be a problem along with the sensor itself.
