S1 wam up regulator
Discussion
I've had the S1 since May; it has never run right, despite visits to 2 local mechanics. There has been a reluctance to rev much beyond 3500rpm under load, a loss of power generally and performance not much better than a 1.5 diesel Citroen! Finally something went AWOL big time, no revs beyond 1800 and a top speed of 35 mph! Something had to be done and the diagnosis is a defective warm up regulator.This seems to fit what the'Bible ' says. Does anyone else have experience of this?
Not sure that the warm up regulator would cause such a catastrophic reduction in power. I think you need to vist a Jetronic Injection specialist who can measure fuel pressures etc..
Have you checked the airway into the air filter box. I know it sounds silly, but i put the intake nozzle on the wrong way round and lost all revs above 3500 on my S1, as it was fouling on the stuff in the way once the bonnet was closed.

the warm up regulator changes the control pressure on top of the metering flap, therefore if the control pressure goes up you get less fuelling and if the control pressure goes down you get more fuelling .. this is classic symptom. All you need to do to prove it is to T a fuel pressure gauge into the pipe from the regulator to the metering head, then open the return from the gauge to bleed pressure from the control circuit (with return hose to fuel tank), as the pressure reduces or increases relative to the pressure you measured before on the metering flap the engine will once again be willing to rev as it should.
