What faults were set? How were the fault codes extracted? Also please repost with the VIN and what history you know of the car and what has been tried to remedy this issue in the past.

hi, the vin is wbafb32010ln83967.the first time the fault occured the engine light came on,when the garage put it onto the computer it said the air mass sencor was at fault so this was replaced and the engine light turned off,then arfter about 10 miles the car started ideling low and cutting out when it stoped, i took the car to a different garage and and when they put it onto the computer it brought up 3 faults.
:140- characteristic thermostat open circuit
:26 - mix adapt 1 {mutiple, bank1} at control stop.
:27 - mix adapt 1 {multiple, bank2} at control stop.
The throtle body was also removed and cleaned at the same time and they reset the idel adaption, the car was road tested and no faults returned but the idel speed is still low.this is the first problom of this type with the car.

Then request the idle speed to be increased by 75 RPM. This can be completed through the GT-1 by most who are skilled with this device.
