Picked up a hired truck today 14 plate atego rigid ( I drive an artic normally honest 
)
Anyway for some reason it’s cutting out when I come to a stop 
Only way it will idle without stopping is to rev it or wedge the throttle open .
Allso it has some kind of tracker thing stuck on the dashboard which buzzes for about 30 seconds every time u start the engine . ( I forgot to take a pic tho )
I don’t know if that’s cutting the engine out for some reason ■■?
There is an amber warning MSS on the dash before you start the engine as well,
Any help much appreciated I did call the hire company but they weren’t much use , said the cutting out was prob some fuel saving thing 
And the tracker was fitted by whoever had it on hire previously 
Cheers mike
