Okay, you can guess/"worry" about the state of your plugwires/plugs/coils
OR
Put on a hoodie, dark sunglasses, a 15 pound chain-style gold necklace and perhaps a fake-mustache and then:
Get in your truck on a moonless night, drive to a deserted area with a slight uphill angle and then:
Accelerate gently until you have to shift to 2nd gear and then:
Once in 2nd, punch the throttle (that means all the way to the floor) and wind 2nd gear out to 6000 rpm. Lift the throttle and push in the clutch at the same time, shifting to 3rd.
IF it didn't hesitate or sputter, your entire ignition system is just fine!!!
Go immediately to the nearest bar to celebrate. It's up to you if you want to wear your disguise in the bar.
Order a water, slam it back, slam the glass down on the bar, leave and drive home because your anxiety over the plug wires has been resolved.
Hope this helps.
