Sometimes when I start the car it starts but then immediatly drops dead...
I can keep it alive by pressing the throttle but when I release it, it dies again.

not that the last 20k km both the steppermotor and the rpm-sensor have been replaced. (because of continuously stalling)

I've put it on diagnostics and the only error that comes up is the RPM-sensor...
Peugeot has looked into it and they simply say they don't know, but could start 'searching' for it (but i'm not planning to pay hours and hours of 'work' and still not have it fixed)

When does the problem occur?
Everytime it has happened was after a cold start (without any problem) then a short drive just a couple streets (like to the gasstation e.g.) but when I try to start it at that moment (so +- 15-25minutes after stopping) it starts and stalls again...

-> resetting ecu doesn't solve it
-> checked all the plugs of the sensors all seem fine (not oxidized or lose or anything)
-> disconnecting battery doesn't solve it
-> it won't even start when I unplug the rpm-sensor, so I doubt this one is faulty
->waiting approx 1h or more and trying again= starts and idles without issues

Another thing to note is that this problem started only a short while after I've put the cat back.. (but then again the lambda-values are/seem fine...)

And something else that caught my eye during diagnostics is that the pre-ignition on idle is very unstable... But this was already present before the stalling started.

I'm getting pretty sick of this unreliable pos so a quick fix is needed really... I need a car for work every day and haven't got the space to keep 2cars or so. Losing the love

So any ideas guys?

most on here know I drive a lesser model :p but indeed its an xu7jp4

lambda values are fine and there is no air leak (this was checked by pug)
exhaust system is the gti6 one, not sure if this matters since I kept the original lambdas.
They also weren't able to check the stepper on it.

Where do I find that power steering sensor? On the compressor itself?
