Anyone know what is wrong with my 306??

I had this with my 1.4L petrol 206.

I had so much replaced on the car I can't even remember it all now. Problem went on for about 6 months - replaced several sensors, coil pack and other various parts. Was told it *might* be the ECU. Ended up spending like £600 and it still wasn't fixed. In the end I gave up and Part ex'd it for a new Kia.

For my car at least the problem started intermittently, then got worse and worse until finally it was basically undriveable.
If you do fix it, let me know. More for idle curiosity than anything else.

[edit: just to add, its basically whenever you press the clutch down my engine would die - so traffic lights became something of a pain in the bum ]

this problem may have been as simple as a faulty clutch pedal switch sensor, located at the top of the pedal box above the clutch pedal.

these are fitted to many vehicles, and are an overlooked part.

i have come accross one in a fiesta that actually prevented idle when the clutch was depressed, but not the normal symptom of one failing, as usually when driving and changing gears the revs will race up rather than dying or killing the engine, this car had been for loads of tests prior and had the majority of sensors replaced, the next call was ecu testing, at a huge cost. i had a quick look knew about these sensors being there, had a spare anyway changed it and it cured it. no fault codes came up when reading the cars ecu.

was a fiesta zetec S on a 55 plate.

At £89 and free husband labour it was an awful lot cheaper than I had feared.

Ouch! Still dear at £89! If, like me, you're as tight as a Jew's waistcoat, you can buy a generic o2 sensor and splice it onto the plug lead from the old sensor. It costs £20 from fleabay for a 4 wire universal zirconia sensor.

^^ If you visit the owners forum you'll see that fitting non-oem lambda sensors to the 306 is NOT a good idea. The problem comes in when one sensor has a linear output and another has a non-linear output or even varying degree's of. Nothing in this case to do with the connector wiring.
The lambda sensor in the 2.0 306 was and I believe still is exclusively available (new) only from Peugeot dealerships. It's a unique design with exact operating specs.
The enthusiasts found that rolling road tests showed significant performance loss from fitting a generic sensor.

On other manufacturers however it's not such an issue and generic sensors are more than adequate
Won't be buying a Peugeot again, so I don't care
