acdii Report post Posted June 17, 2014 Umm, I dont know what plugs were in my first car, but they had to replace all 4 at 4500 miles due to fouling. If those are the correct plugs you refer to and change them out, do a hard reset and see if it makes any difference. Quote Share this post Link to post Share on other sites

Something has changed, maybe the heat range of the plugs are a little different. Either way, if your spark plugs look fouled or in bad condition I'd take it to the Dealer and see what they say. Have you checked your VIN on ETIS to see if any TSB's or Recalls apply to your car?Your Dealer can also run an OASIS report to see if any of those issues apply to your car too.
