I have an 2000 s type jaguar v8. and my codes keep reading Miss firing on 4 and 6. I replace the spark plugs and coils and it's reading the same thing and car is still missing. so i check my sparks plug again and I seen a lilttle moisture on the plug which probably cause them to fold. so then I thought my head might be going bad. but my car is not over heating . could I use a spark plug adadpter to keep the moisture out so that i can buy time to get my head fix.
