Evo 8 cutting out/stalling

Hey everyone, newbie here

I bought my first evo yesterday from Scotland, i test drove it & the car was brilliant, drove all the way back from Scotland to Leeds & again the car was awesome BUT when i drive round town sometimes the car cuts out on idol & when the car is cold & i started it this morning it kept cutting out the idol just drops then stalls but drives without a problem

Can anyone help me please & let me know if this is common or what it could be? all i can think is clean the butterfly valve or get the idol sensor checked?

Any help is much appreciated

You need the base idle reset, this can cure the problem but evo's do this from time to time

I had a problem a few months ago with my Evo IX cutting out at junctions,Chris at AutoTorque did a boost leak smoke test and we found a leak at the plenum manifold to head gasket and the throttle body spindle seals were leaking. I bought a set of uprated seals from Grant at GBEnterprises, Chris fitted those and a new gasket, smoke retest showed no leaks and now no more stalling.

Kieran, take it to a specialist and check they have the equipment to do the smoke test. The machine connects up to the inlet side of the engine, it pressurises it and fills it with smoke, if there are any leaks you can see the pressure drop and smoke comes out of the area that is leaking. It is very common for the throttle spindles to leak, the seals sold by Grant are the uprated ones which hold a higher boost pressure.
