We have this x trail that we started up one morning and revs at 2000 rpm when in park or neutral and hunts slightly. When placed in drive or reverse the revs drop down to 900 rpm.
The car was perfectly fine the day before!!!
No dtc stored no air leaks and fuel trims look good.
I believe you can do a Manuel throttle body reset using the gas pedal etc. Tried this several times and it dosnt seem to work any one else had any joy using this method? or do you have to you use a scanner?? Snap on ultra has no option to do this. Or am i missing something

Any ideas??

Thank you
