300E Spark plugs are very crusty!!!
For about a week now, I noticed my car idling bad and hesitating when I pressd the gas. Well, today I bought a set of Bosch Super H9DCO sparkplugs to replace my H9DC plugs. Well when I took them out they all had oil on the threads, but my #1, #2 and #6 plugs had a very thick crust on the electrode. What could be causing that thick crust build-up on the spark plugs? My old spark plugs were about 3 months old and have about 1000 miles on them.
