Right, me 3.9V8 M reg Disco has over the past few months been stalling
when coming to s stop. Spoke to my tame spanner man and he said "take
the air by pass valve off the plenum chamber and clean and re fit".
Assuming this is the Stepper motor??.
Took it off and it was full of black gunge, unscrewed actual valve
thingy and the rod/spring fell out. Looking at the small screw thread
on it, i'm assuming the motor pulls the plunger up and down. Pushed
rod/spring back in and re assembled (fibre washer fell to bits and i
screwed it in too far and car wouldn't start). A bit of realignment
later and the car starts and does seem alot better. So my questions
are:
A) Should the rod fall out (i'm guessing not)
B) Is the washer importent or will a bit a gakset gunge do the job
C) What price for a new one
