please help with idle problem

[creedy]

my car has started to not idle on start up, it will start and run at 2000rpm then drop slowly then just stall.
its on itb's and has been sat for 3 months doing nothing

Which version of S300 do you have (V1, V2, V3)

[creedy]

v3

[AREA876]

I would start by checking the map sensor because from the datalog I'm not see the map sensor reading change

[creedy]

Map sensor not connected it doesn't use it. I'm running itb's without a vacuum chamber

You must have the MAP sensor connected.

[creedy]

It hasn't had one connected for over a year and worked fine

I'm guessing it's how it was mapped (I know nothing about mapping)

[Spunkster]

You should probably take it back to the tuner to have them take a look.
