Hi Guys
I'm at abit of a loss my car has only done 49000, Ive recently been having issues with misfiring and losing a cylinder. Mostly on cold starts then putting the car under acceleration it has been misfiring and losing power. I have changed my spark plugs to HKS M45XL's and this did fix the issue for a day or two. As soon as the car gets up to temp the issue doesn't occur.
Also when I removed the previous plugs there was quite abit of carbon (Soot) blackening around the plugs.
Any ideas???
 
Are you on the original battery? Mine occasionally did a stuttering start from cold, I replaced the battery 4 months ago and it hasn't reoccurred.
