Hi vonnie17

p1336, p1339, p1340

Engine misfires, could be the coil packs (available here),

the spark plugs - available here (4 required)

and/or damaged valves/low compression. The compression can be tested with a engine compression tester (like this one here).

Or possibly a faulty injector, have a look for C3 injectors if yours need replacing.

Which would also tie-up with your description of lumpy idle and lacks power.


For

P1336 Ignition System Misfire Detected, but there is also a CAM/CRANK sensor fault for this code too.

P1339 Ignition System. Cylinder Number 3 has a misfire detected.

P1340 Ignition System. Cylinder Number 4 has a misfire detected. But also 'Camshaft Position Sensor B circuit Malfunction detected' is also listed for this code.

If you want to find the correct definition for those codes for your particular engine ECU system, use a lexia system (info here) to read the code and get the Citroen description.
