V40 20T auto - warm start problem

v90

Have a 1997 v40 cd auto
when engine is warm it will not start without pressing the throttle
and then leaving it running fast without engaging drive, then after a
few moments it settles to a steady tickover.
I have been told it is the heat sensor sending an incorrect reading
to the coldstart system? but if so is this the same temperature sensor
for the dashboard guage?.

appreciate help
Thanks

check the inlet track for leaks. A weak running engine will do this.
( from experience I had a leak on a flashlube system that caused these
exact symptoms on a V70 1997 2.5 LPT. )

fixing the split pipe fixed it all overnight
