If they can not fault find correctly why are they charing you for it? Does it show a code? Is it a internly fault valve ect?
They said the replacement of the two sensors may not be a fix for the problem but related to the other problem the car had, (It had stalled a couple of times for no apparent reason it happen to my wife while doing, a "U' turn on a highway, not a good thing!) Their hope was it was going to fix both problems.
It did not !
I reckon they are just having a guess, it looks like another trip back, it does make you wonder wether the senors needed replacing at all (expensive) I am certainly no mechanic and I do rely on them as "experts"
