2002 V40 Ignition Coil cracked in half

Post by V40forme »

Mileage~ 110K
I was driving up a hill when I heard a loud pop, lost most power, and the engine sounded like the exhaust came apart or something. Limped home a quarter of a mile.
I looked at my ignition coil, and the cylinder 2,3 coil is cracked in half, almost completely apart at the plug. And the coil's gasket split too.
I ordered new coils, wires, and plugs, thinking this will solve the problem.
I also got codes p0131, p0302, p0303, corresponding to front oxygen sensor, cylinder 2 and 3 misfires.
I'm hoping the coil solves the O2 sensor code too. If that code comes back I'll go from there.
Any thoughts and advice is appreciated. I'm hoping my post might help someone in the future.
Thanks!

Make sure the spark plug under that coil is not loose.
