Re: IAT sensor
The sensor reads air intake temperature. It sends a signal to the ecu so that it can make minor corrections with fuel delivery. It can cause a slight stumble if bad or in your case not even plugged in. What problem are you exactly having Steve? I didn't notice anything out of the ordinary the night that I drove it.
The part number is 37880-PE2-013. I can sell it to you for $44.03
