i think it's likely the new plugs have highlighted a weakness somewhere else in the electrical system that was being masked before by the warmer plugs

battery and coil packs spring to mind for example

well battery has never been changed in 7 years, and i think my coils were changed back in 2007 (perhaps 2008) under a recall. Should either/both have been changed by now???  :confused:

I had them fitted by a very reputable independent specialist in S. Yorkshire, so can't imagine they weren't fitted correctly and/or tightly, although i wouldn't have a clue how to check tbh!!?? Ref the battery, how does one check the life left in one of these??  :rolleye:

My opinion - Go back to these people explain your problem - They should have no problem checking the work they carried out is 100% and also checking to see what your 'new' problem is and if it is related at all. Rather than chase this problme ensure it is not related to the plug change first.

cheers, might well do, as well as check battery life tomorrow, narrow down the list so-to-speak!? Car's, can't live with them, can't live without them!!  :indifferent:

Well bang goes that theory surely!? My 7+ yr battery has a Start Capacity of 84% (Good Battery), and my Alternator Test stated Ripple OK, whatever that means, but showed 14.22 V Good!
Could it just be the fact that its now got colder plugs? Surely though if battery got that much life left, it would have no problem adapting to these colder plugs!? :-o

have you checked your coils?

my 7 year old battery has no problems at all with colder plugs

Perhaps when installing one of the plugs they damaged an electrode, which is why it is not running correctly. I found my car ran better with the 7s than 6s. I tried the 8s for a while but they started to foul so I switched back the 7s and all was good again. If you have your old plugs I would refit them and see if the problem goes away.

Just a quick update on this - I've got an unmapped K03 and i still haven't had any issues with this plug. done over 12k miles on them now. varied driving conditions, but limited spirited driving due to not being able to afford petrol and mainly motorway miles.

i had a single incidence of a misfire whilst sat in traffic a couple of months ago but has not repeated itself since. no fault codes. no problems with cold starting.

I had my BKR8EIX plugs in for a similar mileage on my K03 also, they seemed to work well and have had no misfires but when I checked them recently I found this-



They were massively coke'd up and had loads of carbon deposits. I changed back to the hotter "7" plug and since the engine actually feels like it's got quicker which may have over the last 600 miles burnt off excessive carbon deposits. Worth thinking about, they may not be any noticeable running issues but since changing back the engine seems stronger.
