poor idle/misfire after driving hard

[mememan]

Hi,

I have noticed that my car appears to misfire at low revs and if I blip the throttle but ONLY after I have been driving it hard for a while.

I was erring towards the MAP sensor but my Indy says that wouldnt cause a misfire more likely a stall. However I thought it mightt cause incorrect mixture and thus potentially show this?

It happened the other night in the rain so figured it might be something to do with the HT but then its just happened today in the sunshine after a burn along the A20.

The last Star is throwing the following error code:

ME-SFI 2.6 Motor Electronics

P20B-002 Idle speed control implausible : Short circuit to ground or open circuit.

Could it be something to do with the throttle body itself?

Its a W215 for reference. Indy taking a look now we'll see what star pops up

Would be interested to know if it is the throttle body at fault here...keep us posted.
