The title pretty much says it all. What's the name of the tool used to test the coils on an LS? I don't have a CEL yet, and I've not seen the CEL flash when accelerating, but I have an itching suspension that one is going bad. My MPG has dropped, and the car feels like the transmission is acting up (what others with bad coils have described the car doing).
