Q: van runs lean or low on first start of the day.
the first time I start my van every day, I get a low rough idle for a few minutes. then it is totally fine all day. when I restart my van after having driven at regular distance at normal temp it revs high for a couple seconds and the temp gauge goes up to nearly 3/4's full and steadily lowers to normal temp. perhaps a coolest temperature sensor?
