A common issue with the V12 Aston Martin engine is that the coil packs begin to fail causing a misfire. When ordering replacements you need to know if they are the early 2-pin or later 3-pin versions. The problem is that you can’t know for sure before you start.

Problem is, they are deep in the middle of the cylinder head. Let me show you a trick to get a peek before you start the project.
