Intermittent erratic idling

[Marto]

Morning all,
Since I bought T2S it has been on good behaviour, save for a blown power steering relay.

However in the last couple of weeks it has started to idle erratically, hunting from 550 to 900 rpm. It is doing this only occasionally, but generally when the engine is warm, or has been running rather from cold.

Otherwise the engine is strong and steady and idles happily at 850-900 rpm.

Your diagnosis will be warmly received.

Yours
Marto

Try checking and if necessary resetting the adaptives on the ECU.
