Question about 1991 Peugeot 405
I'm not familiar with the engine in your car, however .. the symptoms you describe could be due to a faulty MAF.
Try disconnecting the electrical wires on your MAF to see if that makes any difference (and maybe clean it..).

You obviously have no warning lights appearing on your dashboard. Sometimes a failing MAF doesn't cause any warning lights to appear.
To be on the safe side, can you get somebody to do a diagnostic check with a hand held scanner- an OBD2 ..? See if any error codes appear.

carb? mono point injection or multi point injection.check for a thin rubber air hose that runs to ign module is it intact or sucking in air caused by being perished also the thin pipe running to the air intake cold /hot ,flap control .if carb then it has a adjusting screw ,and mono point but multipoint is different.91 model also uses a distributor which could be advanced a slightly ,check the same sort of air pipe to the gearbox as iam sure this year has a pipe to operate the gearchange.any of these pipes sucking air can cause your problem

Search 'books' for Peugeot 405 (you will find the Haynes Manual). Make sure you choose the right one for your Year & type (Petrol/Diesel) = the wiring diagrams are in the back. Cost is about £20.
You can also borrow the Manual from your local Library for free ..

SOURCE: Peugeot 405 1993 diesel estate
the alarm control unit is fitted under the drivers seat can be accessed from the rear foot well by putting seat fully forward .unscrew the two nuts holding the cover the relays are inside the unit.
this unit interfaces will tell the fuel stop solenoid to release (by applying 12 volts)
the fuel stop solinoid is on the main diesel pump under the bonnet - the exac location on the pump will depend on the make - but it should be cylindrical and have one wire connected to it - (i dont think peugeot were using multi wired coded soleniods in 93)
obivously if your car has the keypad immobilser you will know where this is - if it is the remote alarm immobilser the reciever is in the over head consol near the interior front light
