After A tune up the car ran worse...So Today My Hubby was out there re checking all his work to try to figure out the problem. He came in and looked at me completly baffled and said, :" I cant find one fo the spark Plugs " Even More baffled than him I went out to see what he meant. This is what I found after groping the engine and Manifold for a while... Mind you this does not look or feel like a spark plug when its dim and on the backside of the engine...

Now if you cant see the problem please turn over all Bonneville parts, keys and titles to a more worthy owner





By the way this is a BRAND NEW Spark Plug Barely in the car for a week.

Looks like it may have been defective or overtightened on install.
