Have a misfire and rough running with loss of power. I have noted the lower sensor only has 1 wire. Is this normal I'm not sure what it's for, I did run over a big log following a bus the other day has it ripped a wire out?

It's the oil pressure sensor, and this is how a blanked cable looks like. The sensor uses only 1 pin.
If you removed the light grey connector, would most likely be one contact plate missing too.

Here it is from another thread looking the same: www.206info.co.uk/Foru...tml#557882

Some newer alternator harnesses also have the signal wire going through such blanked two-pin setups, where only 1 pin actually runs through the plug.

As for the misfire and lack of power, I'd check it in order of least resistance first:
1. Scan for fault codes with Peugeot Planet
2. Check the state of spark plugs (make sure they are Bosch not NGK)
3. Check coil pack
4. Check injectors

Good luck!

Looks like the lambda sensor has been removed at some point - the twisted wires, sheath damage & cable tie all don't look standard.
