Question about 1991 Peugeot 405
I bought a used Peugeot 406 1998 model 2.0. A while back, I took it in to have the cam belt and CVs changed, after that I noticed that the engine will suddenly start revving by itself when it is idle and sometimes when I'm moving. Not long after that, the intstrument cluster stopped working. The only instruments that were functional were the temperature guage and sometimes the fuel guage. I took the car to a Peugot dealer here in South Africa and they changed the ECU, injector valves, clutch systems, fuel pump and speed sensor. They tinkered with the cluster too but could not fix it. I was advised to buy a new cluster. In the meantime, the revving problem was solved but soon afterwards the engine began to cut out in mid trip, on its own, especially when the temperature rises, it feels like the fuel supply suddenly cuts of. I would then have to switch the engine off and restart the car for the engine to pick up again. This will happen 3 or 4 times during my trips and will only stop after I switch off the engine for about 3 hours and it has cooled down. I took it back to Peugeot and they have been running tests but still can't seem to find the fault
Can some one please help?
Put the car on an oscilloscope and check what is happening,check cranksensor,injectors,fuel pump supply,coil packs you will then see what you are loosing if its power(electrical)or a fuel problem put a fuel pressure gauge on it and road test it you will then see whats happening.........oscilloscopes dont tell lies.....
