Message	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: Test Results Label Engine Off Running Cold Warmed Up RPM 0 425-825 600 Airflow 0.57 1.04 0.95 Throttle 0.38-0.4 0.38-0.4 0.38-0.4 Water Temp 75.2 80 174.2 Fuel Temp 71.6 72 77 AAC Valve 0 71 48-62 Timing 16 16 15 O2 ? ? 7-80 O2 RH ? ? 7-80 A/F Base 100 100 97-107 1991 TT Sport 550 turbos 615cc injectors SZ ECU for a 91 5 speed with 615cc injectors and dual pop Selin MAF translator EGR deleted AIV deleted
