Rough idle only on an incline (none of the mechanics I spoke to could help)
Hi
I recently purchased a used 2016 Toyota Aygo Robotic automatic with 120,000 km on it. It really needed a service so I changed the engine oil, oil filter, Transmission oil and air filter. For some weird reason I have a rough idle only and a rough very low acceleration only if my car is at some sort of an incline. I cleaned the throttle body a bit (I could do a bit better by removing it) and the MAF seems pretty clean. I can't figure this out. No codes. Any advice?
(P.S I don't know how to remove the throttle body if that is what you think I need to do. Its a computer controlled one and has two tubes running into it...not sure what they are for. And for some reason 2016 aygo service manuals are insanely difficult to find)
Thank you so much!

Is the problem there since you changed your transmission-fluid (or was it before that too)?
No even before. When I got it, it felt it had some trouble shifting, and the engine sounded a bit off. Now it shifts like a dream and my engine sounds great.
Not sure if this is helpful. but the long trim bank 1 is between -2 and -5 % and short term is -3-3%
very low acceleration only if my car is at some sort of an incline
even with a full tank of fuel?
I wonder if it needs a throttle relearn. You can find videos online how to do this on Toyota. I can't think of anything else other than the throttle body having an issue since it was one thing you serviced.
No codes makes me believe that is working but maybe needs to recalibrate.
@zander916 please use the correct box, instead of hijacking my answer. ok?
Yes even on a full tank....also I did have it relearn the idle. Still does it on an incline or decline.
