After replacing the plugs and reinstalling the coil packs, the car is idling very roughly. I double checked the gaps on the plugs, they were all at.028 (recommended gap). After this didn't solve the problem, I started pulling the pig tails on the coil packs, one at a time to see which cylinder was misfiring. Found 1 & 2 to be dead. Swapped coil packs with 3 & 4, to see if the problem traveled, but it did not. Swapped plugs, for the same reason, and again, no travel.
Which means, I am not getting any power to the coil packs themselves.
Also a buzzing noise has recently started while car is running

Do you
have the same problem?
