Recently I had couple of issues with my car, and non of the recommendations given here worked for me. Today I decided to take off my spark plugs and try to discover what is going on (they only done couple of thousand kilometers). I took off two plugs from 1 & 4 cylinders. And here what I found-I'm posting several pics for both plugs:
Symptoms involve engine management light comes on occasionally, and I lose all power in the accelerator pedal then.
Those plugs are non OEM (I always use them), but they are Bosch with the correct matching part number as they are with two electrodes. They are copper plugs. Those plugs done only couple of thousand kilometers.
Note: Previous plugs changed during the last service had the same contamination issue. So it seems that every time I change plugs, they got fouled quickly for a reason.
The car has been suffering also from a difficult overheating problem, which sounds unsolvable! As I tried most of the common tips. I assumed it could be an incorrect air/fuel mixture (too lean) that are causing the car to run hotter, but after reading the spark plugs, I'm not sure if it is lean or rich! They are fouled anyway. I leave the decision to you!
I have bought new OEM plugs, and they are ready to fit. But I'm afraid to fit them and they get fouled again! I want to fix the issue first.
Best,
M

They look like your engine is running a bit rich, they would be white and clean with no deposits if it was running lean. Maybe the engine temp sensor or o2 sensor is causing the problem, you need to plug it into a diagnostic machine while the eml light is on and that would point you in the right direction.

I doubt it's the plugs with those symptoms .. I'd be happy with plugs that looked like those and would give it an Italian Tune-Up" once in a while.
As Oafie says, you need to get it on a diagnostic.

Are those plugs the correct heat range for the engine?
Where did you get the Bosch part number for those plugs from?

According to this NGK reference, I believe those plugs can't be normal!

Plus I have been running my car for 15 years, and never seen my plugs look like this! May be I went wrong for 15 yrs and now it started to be good

MrBSI, the part number of those plugs is FR8LDCU. They are from a Bosch distributor.

looking at the photo's of your engine you should be using Bosch FR7DE's,

Yes. Oafie, the OEM ones are on my table now. They have the part number you mentioned. But I used to use the FR8LDCU with no problems. Technically, there should be no much different between both. The FR8LDCU are just with 2 electrodes and come pre gapped to 1 cm (that is the U). 7 & 8 are the heat ranges, but the different is so slight.
I bought the OEM plugs just in case, I can still fit them and give them a try, but would this make any risk of damaging the new plugs if there is a problem somewhere???

hi mate, I read somewhere that our engine can be quite fussy with their sparkplugs but if you've been using the FR8LDCU's with no problems then maybe there is something else causing the problem, I would have thought that you would be using a cooler plug in Egypt, we don't get as much sun over here in North Wales.

just a quick question for you, are you running a gas conversion on your car and that's why you need a hotter running plug?

Yes. I know 206 is so sensitive to spark plugs. Even some brands like NGK work like hell with the 206 engine and damage the coil pack.
I have been using FR8LDCU for about 4 yrs with no problem.
Cooler plugs are better in Egypt because of the hot climate. But no one use something different from the manufacturer recommendations (Peugeot here say no need so).
I can fit the OEM ones as they are on my desk now, but I'm afraid to damage them if there is a problem somewhere and I believe the FR8LDCU are not the problem.

Not sure what to suggest now then other than try the new plugs and see what happens or plug the car into a diagnostic machine and see if there is something amiss with one of the sensors on the engine.
good luck and let us know how you get on with it.

Ok. But we should not expect too much with the diag test in old 206 models!

Your local Peugeot dealer will have the proper test equipment to see what's going on, even the older models.
