Gen 3 Engine Managment light

Check the MAP sensor too, make sure the port is clear.
It should throw a P0105 code if the ECU decides that the pressure readings are way off, but if it is sluggish because the port is blocked it might cause your symptoms.

Changed my throttle body other week 
I think I may have seen where it recirculates into the Inlet 
Maybe you could guide a thin wire in and give it a good wiggle 
Without removing Inlet manifold 

Just a thought 

A "frayed out" inner cable from an old bowden cable (clutch cable or similar) in a power drill at low rpm does a fairly good job, but there are bends that even that can't get around, like the ones in the exhaust side of the passage.

I would say a gear cable from a push bike 
this would be more flexible 

Thanks for the advice, quick update.

Took everything (except exhaust manifold off Friday and cleaned all out) there were no obviousl blockages but it's difficult to check where the egr is mounted.

Light stayed off for long drives on Fri and Sat, thought I'd fixed it but came back on today, grrrrr.

The MAP sensor works (I can check via the OBD) but is it possible due to being 20yrs old it has lost some sensititvty? (I've replaced the EGR and cleaned everything so I guess the only other option is an electricasl fault not triggering the EGR which would be vewry difficult to find.

Just to circle back to this.

I couldn't solve it so removed the engine light from the dash for his driving test (he passed)

However I couldn't do this for the MOT and they diagnosed it as a duff Lambda sensor (I bought some from ebay supposidly for the Jimny, lesson learnt).

All good now
