Your local Peugeot dealer will have the proper test equipment to see what's going on, even the older models.
My experience tell me that the Peugeot Diagnosis equipment don't work well with old models. Actually, show nothing! But let's see.
I'm suspecting couple of things like the O2 sensor. It was changed 5 years ago and I used a non OEM sensor. It was NGK.

Block the end with a rag while a mate looks in the engine bay and under the car. An exhaust leak, even a tiny one, will probably make your engine run rich.

If they (you) are using official Planet Peugeot diagnostics then it will work ...
They are either not connecting it properly, using the wrong cables or using other software which isn't compatible ...

Thanks for the contribution Gazza82. This is a general problem for the semi multiplex. No sufficient information, or all problems are fall under "Mixture Regulation Function" fault! I had different problems with the crank sensor, Lambada, stepper...etc. Non of them was discovered through a diagnosis test by the Peugeot diagnosis equipment. The dealer has the original equipment, original cable, and the updated software. What could a fault named mixture regulation function mean? It could mean bad plugs, bad coil, or one of injection calculation sensors is playing with the air/fuel mixture. So such a message lead to no accurate fault find. And you still have to run more tests on various parts individually.
I trained in Peugeot as a mech engineer when I finished my graduation in 2003. And have seen such things many! Last edited by hamed206 on Fri Nov 21, 2014 6:35 pm; edited 1 time in total

Good thing to look for Kandlbarrett. I really have tried different things, and non of them seems working.
Also when car is running rich, and it gets the plugs fouled with deposits and carbon (like the picture) do you need to change the plugs? Or you can fix the root cause of the problem and run with the same plugs?
This is an important thing I need to know. Because if I swapped new plugs now, and they got fouled again, does this mean they are ruined? Or can be cleaned and re used?

no the plugs are not ruined, just give a gentle clean with a wire brush.

Thanks this means that I can give the new OEM plugs a try with no fear they can be damaged. Last edited by hamed206 on Sat Nov 22, 2014 7:28 am; edited 1 time in total
#23: Re: Here is My Spark Plug Reading Condition-What do you see? Author: hamed206, Location: EgyptPosted: Sat Nov 22, 2014 7:25 am ---- I have a slight internal oil leak! Sounds that piston rings started to wear! Could this be a part of the problem? I mean oil entering combustion can foul spark plugs. I'm not sure if this can cause a situation like in the pictures above. Are plugs fouled because of excess carbon related to air/fuel mixture problem? Or oil entering the combustion?
#24: Re: Here is My Spark Plug Reading Condition-What do you see? Author: Oafie, Location: Glyn CeiriogPosted: Sat Nov 22, 2014 8:18 am ---- I'm not sure either, I thought oil being burnt would leave them black and sort of greasy looking.
plus you would have blue, grey smoke coming out of the exhaust

No permanent smoke blue or grey. But the tail pipe is full of black!
#26: Re: Here is My Spark Plug Reading Condition-What do you see? Author: hamed206, Location: EgyptPosted: Sat Nov 22, 2014 12:12 pm ---- Update:
I have been able to put the car on a diagnosis test today. And unfortunately, it showed nothing on the test. Also all reading parameters are good this include both MAP & O2 sensors.
They have also tried a new coil pack, but didn't work. There is an excess "black" smoke coming from the exhaust and a smell of unburned fuel which become noticeable.
The engineer told me that he see no problem on the test, but the car is performing like a crap! And it is not burning fuel at all. So he suggested two things: try the new plugs (which I will do it tomorrow) and if the problem persist, it left nothing but the ECU
My ECU was replaced with a re conditioned one from ecu-testing 4 years ago. I bought it for 200GBP from ebay. If the problem turned out to be "ECU" any suggestions for where to get another one which is price reasonable? Mine is Magnet Marelli IAW 1AP.81
Last thing to mention, MAP sensor was reading 973 during the test at idle! While O2 was reading 996.
Best.

Car cut out several times today when idling. Engine management like come on while driving and I lose all power in the accelerator pedal for seconds, then it return to normal but the fan kicks!!! Many things are playing up together. Fan kicks, engine management light come on and off, car hesitates, poor overall performance and acceleration, also the car overheats on the high way. No one really is able to help or to advise about something.
