Mysterious coil
#7
Managed to blow up pix. It appears to be and ignition coil. But not for 05 Deville. The Northstar ignition coil is service as a assembly of 4 coils. The Cadillac V6 uses individual coils. Coils and module come off valve covers as assembly.

These are the coils that were in my car. It ran perfect with them. But now #5 is misfiring. Replaced all coils on the back bank like you are talking about. Ran perfect for about 30 min on the way home. Turned off and started again about 2 hours later and it started missing again. Same #5! Check engine light flashing! Wth???
