DodgyRog Posted February 23, 2014 Share Posted February 23, 2014 Quick background I had a Coolant leak from the pipe at the rear of the head and it got into the Sparkplug wells 5+6 and over the Coilpacks I have dried it out, but still have a misfire on full boost , the misfire starts as soon as the 2nd turbo kicks in if your foot is to the floor, lift off a bit and it's fine Anyway, the Iridium plugs are pretty Black, I am guessing this is due to the misfire, so can you clean them I was hoping to clean them to see if it cures the misfire, rather than spending £45 on a new set, but not sure how or if it can be done What's the chance of it being a Coilpack issue after them getting covered in coolant? I have Googled it, but no definitive answer, just I did this blah blah, but no one saying it worked long term Quote Link to comment Share on other sites More sharing options...
Mk4Gaz Posted February 23, 2014 Share Posted February 23, 2014 I'd maybe suggest chucking a couple of cheap copper core plugs in the affected cylinders, and trying that first rog. They're only a couple of quid each, and will rule them iridium plugs out, without risking damaging the tips first Quote Link to comment Share on other sites More sharing options...
fastcar Posted February 23, 2014 Share Posted February 23, 2014 What level of boost are you running as I have a couple of new iridium plugs you can have but the are only good for stock level TT so anything more then that you will get a misfire. The heat or cold range is 11 if they are any good to you, you can have them for price of shipping as they are no use to me Quote Link to comment Share on other sites More sharing options...

Got there before my bud Thanks anyway:d Thanks for the offer, but I am running between 1.1 to 1.2 Bar, depending on the Air Temp Yeah won't be any good for that level of boost Going to get some cheap copper plugs to try I think but I also going to see if anyone has some spare Coilpacks, after doing some searching, it seems likely to be a coilpack starting to degrade Quote Link to comment Share on other sites More sharing options...
