I tested my ignition coils this past weekend, sure enough the #4 coil is kaput (or heat sensitive, starts to work when car heats up)

I measure the following with the engine cold:

Cylinders #1, #3, & #5: between 2 and 4 ohms.
Cylinder #2: 124K ohms (way too high...) and I suspect it's on it's way out.
Cylinder #4: open circuit.

I didn't bother to re-measure with the car warmed up, I know that #4 is really bad since I can disconnect the injector and have no effect.

I couldn't find the Bentely recommended resistance for the coils packs, does any one know them? Although I'm assuming coils 1,3,5 are ok, I wonder if I should change all 5 of them? While I'm at it.

Any good source for replacement coils at a decent price?

Thanks for any help.

Cheers, /James.
