#1: Here is My Spark Plug Reading Condition-What do you see? Author: hamed206, Location: EgyptPosted: Wed Nov 19, 2014 7:39 am ---- 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

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.

As Oafie says, you need to get it on a diagnostic.

Where did you get the Bosch part number for those plugs from?

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.

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??? Last edited by hamed206 on Wed Nov 19, 2014 12:04 pm; edited 1 time in total

#10: Re: Here is My Spark Plug Reading Condition-What do you see? Author: Oafie, Location: Glyn CeiriogPosted: Wed Nov 19, 2014 12:05 pm ---- 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.

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!
