WS WT fiesta rough idle limp home mode stalling ? This is why

[firko]

Gday all,
been extremely frustrating trying to track down my idle and stalling problem on the missus ws fiesta 1.6, finally we have fixed the problem after cleaning throttle body injectors and spark plugs it came to the throttle position sensor, unfortunately it is also the throttle body in one as well ford are asking $300 where as i found one at the wrecker for $135
, ultimately it was the obdII that found the problem to took me a while to fine someone who could run the test who was not going to charge $100 for 2 min job,
to replace this part is very fast and easy took all of 10 min, the problems we experienced were
rough idle stated off like bas spark plugs and got worse and worse to the point it would stall ever set of traffic lights (took about 6 weeks to get that bad) then we started getting stuck in limp home mode so got stuck in and fixed it.
this is something almost anyone can do themselves
