Hello - I have bought a 2010 GX460 a couple of years back and for the past years, I've been dealing with this check engine issue that typically used to show up and go away weeks on end until now when it flares up multiple times a day. The engine will idle high in neutral and will try to rev (pull forward) when slowing down. Also lacks power when revving. Car sounds don't change when I unplug the sensor. I have already: - Changed EGR and cleaned connections -Cleaned out filters and Airflow system -Took to the dealership (they couldn't tell me a thing) -ran some seafoam through it -checked all valves and tubes for cracks or loose ends. I haven't swapped the MAP sensor yet bc the dealership told me that wasn't the problem (although I'm suspicious) I also suspect the plug wiring to be an issue Looking for all the help I can get.
