Peugeot 307, Rough Idle, Help

ntgar

Hello,

I have a Peugeot 307 1.4 16v,

Two weeks ago it developed a misfire it was very bad engine light and anti pollution fault came up on dash, plugged in in diagnostics and said coil failure so i changed the coil car ran fine then yesterday it developed a rough idle but drives ok, engine light flashed and beeped and then stayed on fault code was P1336 and Anti pollution came up on a dash again so i changed the the crankshaft sensor hoping that would do the trick but no joy, just wondering anyone any ideas, thanks for any help.

Might be a timing belt problem

As below check/replace plugs,Also check resistance on each injector,each one should read around 14ohms...if all is o.k check wiring back to ecu.



Fault code P1336
After sales description of the fault code Considerable misfiring on several cylinders : Not characterised
Description of the diagnostics The value of the upstream oxygen sensor at its limit (high or low) is above or below the expected value
Conditions of activation of the diagnostics engine running
Conditions of disappearance of the fault 3 starts and then stops of the engine without the fault being present
Down-grade modes if fault present Deactivation of the EOBD diagnostics upstream oxygen sensor
Switching on of the warning light and/or warning message Warning lamp MIL
Main customer complaints likely Switching on of the warning lamp possible
Down-graded emission control
Lack of power
Suspect areas Check that the system has not produced any other faults, especially at the injectors and coils
Check or replace the spark plugs, injectors and interference suppression
Check the engine compressions and for any inlet leaks
