| I'm still working out the bugs in my car, and the problem I'm trying to solve now involves the idle. When I start the car when it's cold, it won't idle. I have to keep my foot on the gas or else it stalls immediately. Once the car warms up it's able to hold an idle, around 600 rpm. It seems to drive fine. I hooked up Nissan Data Scan to look at the sensor values to see what it's doing. Here are some details:
