I just got my st170 estate today in grey done 78k ffsh and top condition, drove it home and it felt a bit sluggish, checked the so called imrc and found the cable disconnected from the dsi with a cable tie wrapped around the nipple the cable clips onto. So I fit the cable back on and the car sounds and goes much better, looking through the service bills when serviced in January this year at ford there is a note saying imrc needs further investigation and may need replacing. Just wondered why cable would have been disconnected and a cable tie on the dsi. Cheers ste
