I'm having a strange problem since getting my car back from MOT,

For some reason as I'm coming to a stop so clutch in and drop to neutral for SS, my engine start slowly auto revving it's setup up to 2000 RPM, when I'm at a Stop it will hold the engine at 2k RPM until i heal toe from the break to the accelerator and just tap it then revs will shoot up and drop back down to normal idle at ~1250 rpm,

i have just replaced the air filter, and am about to replace all spark plugs, oil filter and perform an oil change on it as it's just passed 56k miles this year, but was wondering if anyone else has had this or if there is a Diagnostic / MOT mode to hold it at 2k for imitations test and the MOT station have not turned it off, seems a bit strange that this has just started after the MOT but could be a coincidence.

Make sure the throttle actuator is free on the inlet

Turns out it was the spark plugs replacing them has solved the issue, 1 and 4 were looking rather bad.
