1996 ford explorer Ignition coil pack specification
I tested the resistance on the secondary side of the coil pack. The manual tells me it needs to be between 6K-10k ohms. I am getting a reading of about 15k ohms but it is on all four secondaries. (5.0 L V8). It seems odd that the values would be thsis far off on all of them at once. Like it is somehow wearing out slowly versus a failure on one coil. Is this how coil packs go bad? slowly. Thnaks.

Reason: more specific title
In my opinion, replace them. If they are not within factory spec, they are probably effecting performance.
About a year ago I bought Accel ignition coils. My factory coils were within tolerance, but I replaced them anyway. I did notice a slight gain in performance over stock. But maybe that was a sign that my factory coils were indeed, going bad. Or maybe they are better. Anyones guess. Good luck.
