Spark Plugs too black
Posted: Sun Jan 30, 2011 1:01 am
Hello
I put new spark plugs on my 3.9 EFI V8 engine and have one problem.
When i took off the spark plugs i saw that they are too black . It isn´t normal,right? Maybe very rich petrol mixture ?? How i can put a good petrol mixture?
thank you and sorry my english
