1998 ford ranger, number 3 cylinder mis fires.

I will read the SM service manual to you now.
firing order 1,3,4,2
most cars with old coil packs 4 cylinders is just one pack
not coils but yes 2 coils in 1 pack run 4 cylinders, using wasted spark tech.
oops this old dog run 8 spark plugs now that is different.
and here it is from the book
we do know 1 and 4 fire as one and 3 and 2 first as one pair too.
I sure hope the 2 coils fire, the same way.
no lag. coil 1 spark 1, to coil 2 spark 1. hummmmm
yes tricky see these sage words. from the SM

Dual Plug Inhibit (DPI) is a function of the powertrain control module that is used when the vehicle is being started. During engine cranking, the powertrain control module will only fire the spark plugs on the right-hand side of the engine.Whenthe engine has started, the powertrain control module will start normal twin-plug operation.

If # 3 cylinder has spark at the plug it must fire if the following conditions apply. Injector is supplying fuel to the cylinder. and cylinder compression tests OK . So check above ,one or both must be at fault.

this code identifies that the computer in your vehicle has picked up that cylinder 3 is not fireing properly so i would say change the plug in cylinder 3 if not cured change the plug lead if thes dosent work then distributer cap or the electronic distributer check all these things in this order its just elimination really

code says #3 cylinder misfire, check the coil pack for this cylinder to see if its got spark, bad o2 sensor will spit another code, its most likely the coil

most likely the coil or ignition module

That is a cylinder misfire code have you had the plugs changed, could be a bad plug maybe bad coil, or injector how does it run
