    Have the temp "sensor" checked with a scanner, engine needs to be cold! Or the next time this happens, unplug the sensor and try it.

    thanks as every bit of info is appreciated..I did just replace coolant temp sensor..no help. there is also an ambient sensor ahead of air filter..??? nissan suggests to hold throttle 1/3 down when starting cold..I'll let you know.

    Well just move further south! Still need to know the readings on the sensor, should be ambient cold.

    ok! I have 7.8 ohms at 5 degrees ambient about 2.5 at 65 degrees..now that I hold about 1/3 throttle as I crank she starts, goes right to high idle..seems wrong to have to do this to a F I vehicle??
