coil

i have a 2001 cv and it started missing 2 months ago an ford charged me 316 dollars to replace a coil and plug it's doing it again an i live on social security an need help . how do you check a coil to see if it is bad or find the bad one. help appreciated jim

well first off welcome to the site

ok now the best thing i can tell you to do is not goto the dealer for stuff like this but find a good local shop and deal with them

the coils are about 40 - 50 bucks depending on where you get them but napa always seems to have some in stock

next off to find the bad coil you should use a code scaner for OBD 2 and it will tell you what cylinder has a miss.

then take that coil off and swap it with another one that was not reporting a miss.
If the miss travels to the new location then you have found your coil. if not try a new spark plug in the cylinder that has a miss

hope this helps ya

Finding the bad one is the first step.
Some auto parts places offer a free code check that may help to pinpoint it.
If there scanner is good it will give a code no for the cylinder that is miss firing.
Also disconnecting the electrical to them one at a time may help find it.
And electrical connectors are sometimes the problem.
Make sure they are all plugged on good.
If you need more help post back
Good luck

You may have to find a good repair shop with a good engine capable scanner.
A good scanner that records history codes should be able to find the bad cylinder and some good scanners can run coil and injector test.
Good luck

thanks for the answers , since a scanner has been used an no codes were registered an the check engine light did not come on either time, i guess it is back to ford when i save enough money.most of the time it does not miss unless under a slight pull, so will be hard to diagnose when setting still. again i appreciate the help jim

You are welcome.
But the key is a good engine capable scanner.
Not all scanners will read history codes or miss fires or do coil and ign and injector test.
You will need to find a good high end scanner.
Also make sure you have good OEM type Motorcraft plugs in it.
How old/mileage and what kind of plug do you have in it?
Also you might look around for a good repair shop.
Many of them can do work like that.
Good luck MT

Here are some tips on finding good ones.
Check around Ask around
Word of mouth.
Family friends coworkers neighbors business people and delivery people.
Mailmen and parcel delivery people get around and notice a lot of stuff.
Even a good parts house knows what shops are good and not good.
Chamber of commerce and better business bureau and city hall.
If you find a good referral to a repair shop go look them over and talk to them.
Look for a clean looking busy place with nice people running it.
Ask a few questions and ask about their qualifications and training.
Not all places have trained tech/mechanics.
If they do not find a place that does.
Even all dealers do not have all trained techs/mechanics.
