Angry Cylinder 7 misfire (errr)

After preaching the love for theses cars, I was driving my silver baby. I hit the gas really hard and the check engine light came on and it says (Cylinder 7 misfire) I reset it, **** it down and it came on instantly.. Ill drop it off next week to see whats up. The coil packs have been changed about 10 ago. smh.. I think the Pressertech upgrade may have fouled the plug.. I hope, I hope.


Still got much love for the CL600

diagnosing misfires on these engines is pretty straightforward

swap the coil to a new cylinder and see if the problem follows

if the plugs have 50k miles or more I’d change them anyways
