Coils interchangeable?
Are round and square coils interchangeable? Looking to diagnose a misfire by replacing half the coils with some spares.

Re: Coils interchangeable?
I think the plugs are the same, but they have different mounting holes. I just replaced all 4 with harness and bracket. That didn’t solve my misfire. Turns out the spark plugs were cracked. I must have done that during the swap.

Re: Coils interchangeable?
Replaced the cracked spark plugs and the misfire codes went away, gas mileage went up, no more shake or shake on acceleration. But if I pull up the misfire counter I see that misfires are being detected. There aren't enough to set a code. Is it normal? How would I fix this?

Re: Coils interchangeable?
I changed the spark plug wires all the way around, ran some fuel injector cleaner, and I changed the oil. Thats about it.
