Default HELP with Ignition Coils

What is the OHMS over the GM 2006 Z06 Ignition Coils when taked out of the car.
There are 4 leads on the coil and Im checking 1 and 4 with my meter.
What should it read?

I have no codes, but the car on the computer shows that the timing drops like a heart beat. I replaced the plugs, plug wires and now checking the coils. At idle, to problems.

Any HELP??

Could I have a valve issue?

What do you mean "like a heartbeat"? When My car is brought to a stop at a traffic light or in the garage (still running) after (guessing here) 15 seconds, or so, of idle the engine kinda makes a sound, I see the tach move up a few rpms and then the tach actually slows down more than it initially was at idle. On my EFILive the event shows in the idle, A/F and some other field but there is nothing wrong with the car.

Is that what you are seeing? I think that is actually quite normal for the cars.
