xantia 1.8 8v idle - meeper
I have a 1993 xantia with the 1.8 8v engine. It occasionaly refuses to start without use of the throttle, and once started will not idle (stalls) if throttle is not used. Leaving the car for a few hours and it will start again normally with no throttle.

Reading from this forum and others I read that the "throttle bypass valve stepper motor" aka "idle stepper motor" on this engine is prone to failure. Does this sound like a likely diagnosis to anyone or should I be looking at something else?

Anyone know if this part is easy to change or best left to my local dealer?

Thanks in advance,

M.

Hi Meeper

Almost certainly the stepper motor. My 1.8 Xantia used to do the same. Taking it out and cleaning it with WD 40 worked for a while, but in the end I bought a new motor. It's a cylindrical thingy on the inlet manifold. Just undo the screws, disconnect the terminal block. Take care and get the right replacement - Xantias used 2 or 3 different types. Mine was a Marelli, but I think there was a Bosch type fitted (not interchangeable)

Buy your replacement through an Auto electrican. You'll pay less than getting it from a dealer. They are about £70-£80.

Graeme,

Many thanks for the help, found the part in the end, around 90 from a friendly citroen dealer; works like a dream.

Cheers,

Mark.
