This scan tool I borrowed does not seem to be able to display what the IAC is up to, but I am still learning how to use it. As for the LTFT... I got a data log of it happening. I started the log and took the RPM over the magic 2000 RPM. In frame 7 you can see I have taken my foot off the gas pedal and I am coasting, I am still doing about 55 MPH and the engine is surging from around 1500 to just over 2000. As I slow down to a stop the surging settles and builds up to about 2300 RPM and will drop to idle from there once fully stopped. What I notice is that the LTFT Bank 2 goes higher suddenly. Prior to frame 5 it averages about 2%. I also noted that Bank 2 Sensor 1 % dropped about the same time. So... O2 sensor maybe? Thank You!!!
