My check engine light came on today and I went through the diagnostic codes and came up with PO357 on my 2002 ZO6
I tried to do some research on the forum but only see treads about changing the spark plugs and plug wires. Is that the first thing I should do? What is circuit #7 and location?

faulty coil? cyl 7.
rear left side?

just thinking out loud but thatd be my guess

Thanks, jnealg!
Can anyone help me with the correct location of coil #7 ?

Coil 7 is on the driver side and the one closest to the firewall.
