I have a 1999.5 Pathfinder XE with about 130,000 KMS on it.
I have one small problem with the idle on start up. This summer I started experiencing high idle on startup. This took place on most mornings and a little on hot days. I believe it has something to do with a sensor, for some reason the computer thinks it's very cold out and idles the engine high to warm it up? When in this condition the idle will not come down with a little blip of the throttle. Any ideas?
Could this be something to do with mass air flow sensor?
I also remember reading something about a temperature sensor inside the airbox?
Any truth to this?
Any help is appreciated,
Thanks,
alm
