changing the coil

the engine on my 1999 Ford Ranger was misfiring, not all the time, but usually at highway speed. Took it in and had it checked, and they say its the coil, and the spark plug wires. Can anyone tell me how to change the coil? I can do the plug wires, but have no idea how to change the coil. Can anyone help me out?

Welcome to FTE!

First thing that would help some people help you would be if you posted which engine you have in your truck.

I've replaced coils on distributor ignitions. They are usually easy to find by following the plug wire that doesn't go back to a spark plug. On a distributorless ignition, I'm not sure, but chances are someone on here has done it.

engine, coil

I know it's a V6, and it's distibutorless. I really don't know any more details though.

You need to tell these guru's what engine you have. If you can't see the coil then you probably have a distributorless ignition system. I'm no expert but my guess the coils are in the ignition coil pack. Trace the spark plug wires back to their origin and your there.

ok, i've got a detailed description.
1999 Ford Ranger, 3.0L V6 EFI Flex
Hope that helps.

Is there a coil for each cylinder, in the coil pack, or just one coil, and is it difficult to remove the coil and replace it, etc.
Thanks in advance.

There are actually 3 secondary coils, each coil fires 2 plugs in series at the same time. It should be easy to change out the
coil pack. There are 6 plug wires, and a connector that goes to
the PCM that fire the coils.

coils

so, i cant replace the individual coils? Instead I just replace the whole pack? Thanks for the info, it was very helpful. How much does a coil or coilpack cost, generally?
