In some old threads you'll see i've had this problem and did the code 42 fix as attached - which did solve the symptoms , i.e low idle speeds and power steering problems , yet i'm not 100% happy as every now and again its as if the cars not quite right so if i was you i wouldn't bodge it -which this fix is in a fashion .

i'd go for a thor delimeter as these are the ones that sort power steering too
