With the replacement of the TB(throttle body), the TPS(throttle position sensor) was also replaced as it comes with it.

strange thing is that warped throttle body would normally cause a high idle

 

I would invest in the ACR - anything else sensors wise is just guessing and you just end up blindly replacing sensors

 

in the meantime make sure that everything is in good serviceable condition, including all the earth points, spark plug gaps, rocker clearance, make sure all the sensors (including the cam sensor at the rear of the engine) are all clean, in good condition and well seated. Check the loom over looking for squashed bits or damage -  pay close attention to the rear of the throttle body/manifold area

Thanks Ivan - I will do all those AND get the ACR. Can you advise which specific one (ACR) I need? Is there a particular model number? Thanks.

There’s a pinned thread that I added to some years ago which has the part numbers.

You need to reset the IACV and then when warmed up set it up.

Great - thanks Flying Scot. I've dropped the car to a garage with Mini diagnostics, so hopefully they will identify the problem in the short term. Then, I'll make an investment in the ACR.
