its an electronic pedal type ..fix is.. replace the pedal sensor asap

your description of this fault is scary and sounds dangerous

Could be wrong one. Get one that is exactly similar end to end.

try ebay adds, or join peugeot public service box and see the diagram

I suggest you get one of those manuals people get nowadays to
do it yourself.. My brother use it to repair my car and it's totally repaired now. he got it from. www.reliable-store.com

yes, and there are four injectors in peugeot 307 hdi 1.4.

These are prone to the pump in the fuel tank failing,

The electrovalve that controls the turbo waste gate needs to be changed it costs around £40. It is located on the front lower part of the engine block. I have done lots of them they are a common fault after about 50000 miles.

usually you should do it for peugeot diesel at 122000 miles along with water pump and the tensioner roller that runs under the cambelt too. But to be on the safe side do it at 100000 and save the fortune.
It took me (DIY job) about 6-8 hours as i wanted to save 450 pounds.

I had same problems with my 307 hdi, turned out that the additive which drips into fuel was empty and changed particle filter,problems solved
