Hi guys,
I have the p1320 code. The car is running really smooth and not misfiring.

I tested all the original ignition coils and here are the resistances I measured on 5 of the 6 coils:
4.35, 3.7, 3.6, 4.7 and 4.9

Are these resistances good?

I bought the Hitachi coils and got the following readings 10.3, 10.6, 10.7, 10.9 and 11
I don't want to spend $300 on coils if that's not the problem.

Please advise.
