Hi, sorry if the data you have put on would rule this one out, or if you have already tried and ruled it out before moving onto mor involved things..... im not so great with newer cars and many sensors, but I had similar issues with mine about 6 months ago. It would be lumpy under load and idle would rise to nearly 1250.

It turned out to be HT leads were damaged and arcing out to each other causing it to be a very confused ECU resorting to odd maps. Replaced with new and all is well. annoyingly they rub when driving, a few cheep clips to keep the new ones separate and 6 months on still fine.

Also on account of troublesome, they can have there moments, but the majority of parts are cheep, Ive found mine behaves far better with more use, compared to newer cars are more simplistic, compared to classics are far more reliable, and compared to rust issues on the sluggish MX5 and potential engine failure from a dodgy cat on MR2s.... HGF aside are quite reliable. Once through this rough patch im sure you will love it and it will love you back by behaving
