Hi I'm Roy. New to this site and looking for help.

Proud owner of a st170

So the story starts with eml light coming on and after taking it to be read at a garage it was lambda sensor 1 so I had replaced at a cost of £155 all in. The old one had snapped! Ok replaced with a Denso sensor

So 2 days later the elm light rears it ugly yellow glow again

Take it back to the garage and he says that it is sensor 2 this time the rear one. Ok so I go to the parts shop myself and buy a Bosch lambda sensor 2 and get under car to fit it.



Find out the second sensor is rubbing on the drive shaft where the wires come out of the top. Ok. Find that the cat bracket has snapped on the cat side and and bracket side. Sorted the new bracket and having the cat side welded up.

Problem is the new sensor 2 I have bought is 15 mm longer than the original ford part. And I know from taking off the cat that fitting new bracket and putting cat back on won't give the clearance needed to fit new sensor!? So how do garages fit these sensors if they run so close to the driveshaft? Can I plug original second sensor hole and drill and weld new thread in a slightly different position ?

Plus because the garage used a Denso sensor 1 did this throw a fault with the second sensor because the second sensor is original ford part?? Is the sencond sensor damaged enough to give a fault?

Problem 2 started way before this and it goes like this..

Only under load/acceleration the is a bad wobble throughout whole car mainly above 30 mph when accelerating at any rate. All ok on braking and deacceleration. Does anyone have any experience with this? I have checked drive shafts for play and seem fine

Any advice on these problems would be great )))

Thanks Roy.
