Default Anti pollution fault

The dreaded Anti pollution Fault strikes again >

It happend 3 times in the last week, every time when sitting in heavy traffic, with the aircon on, these are not coil failures, when the vehicle is switched off and restarted it goes well. (I replaced all 6 coils last year with the new design coils)

I had the timing belt replaced 2 weeks ago, but when I looked through the maintenance book I found that the spark plugs and fuel filter have never been replaced (so much for a maintenance plan :-\). Could this be the cause?

Struck again !!
This time not in heavy traffic, in fact no traffic at all doing 100km/hr.

By means of elimination I have ruled out the coils, the following items are suspect:
1. Fuel, started filling up at a station close to my work, 95RON
2. Spark plugs, never replaced in 108 000km.
3. O2 Sensors.

So I purchased the spark plugs (from Peugeot naturally) they only had 4 in stock.

I decided to start at the back 3 as this is the most work, After removal of the air intake manifold (1.5hrs) I could get access to the coils and plugs, I also decided to swop the coils around as the rear ones are always operating at a higher temp sitting under the inlet manifold, anyways I removed the plugs and I think I might have found the problem, one plug was completely "burnt" away!!

With the new 4 plugs the car performance is already better, so much for Citroen and theit 120 000km plug change.

I also spoke to a Peugeot mechanic, and he recommend that the plugs be changed at 60 000km

The installed plugs are Bosch FR8 SPP332, and the part number is 5960.81. I tried shopping around for the standard or the Denso equivalent, however I could only find the Bosch plugs from the Peugeot dealer.

Back to work tomorrow and hopefully the problem will be fixed
