Well guess it was bound to happen, but i am now a victim to bad coils. I was driving down the freeway i punched it and she started hesitating and the lost some power. The check engine light came on i was like no why me. I took it in to autozone and the diagnostic said misfire in the #6 cylinder. I just spent alot of cash on a new soundsytem and intake. I did my research and found a tech article http://www.lincolnvscadillac.com/tech/Lincoln-LS/IgnitionCoilV8/
It seems like a fairly easy DIY job, i hope so. I don't have much money to spend as of now so im just goin to buy one coil and replace it. First though can anyone tell me what a proper reading should be for a good coil when i test it with the ohm-meter. I believe this car has allready had its tune up, so if the sparkplugs good which they should be i have a bad coil. I have to get this fixed asap good thing im off of work tomorrow. I have one day to fix it, this seems to be a little annoying problem the ls faces but no biggie from what i can tell. Has anyone heard the word out there about there being some aftermarket coils available. Later on when i have some money put up i'd like to upgrade to those if there is such a thing.
 
Alnih, we all feel your pain.. But as of right now, there isn't a way to pull out your coil and put it through a test to find out if it's old or bad. A "good" coil will have the same resistance as a "bad" coil. You'll have to put it through a coil load test at the dealership while it's still in the engine. My autoenginuity scantool is able to do this (After I finally figured out what to look for).

One posted that you "could" hypothetically could warm up the coils in the engine and then pull them out really really fast and test them. But it was just a "thought".

Changing out the coils are a 3-4 on a scale of 1-10 if you have a V8, which from your post I assume you do.. If you have a V6, well sorry for ya.
 
When you change it be sure to check ALL of the coils for oil contamination. If there is any oil down in the holes roll up several paper towels and stick them down into the plug holes to soak up the oil. Get out as much as you can, and order a new set of valve cover gaskets ASAP.
 
Thanx for all the extra lil tips, im waiting for my roommate to finish up in the garage and im bout to take her in there. Im just goin to buy one coil as of now, and hopefully there is no oil down in there. It looks like a fairly easy job just a tight space to work in. Im used to that try working on the VG30deTT engine bay. Thats hell, i believe i can get this one done. I have to get started soon im not sure how long this will take me. I hope this works and i don't have a misfire, im not sure how accurate those autozone diagnostics are. Since there aren't any aftermarket coils out there im just goin to take whatever they offer me. If i run into any problems i'll let you guys know. Again thanx for any help....it's very appreciated..
 
^^^^ Yeah it can be done for the V6 just is more of a pain in the ass. Here is the tech article for the V6 http://www.lincolnvscadillac.com/tech/Lincoln-LS/IgnitionCoil00-02V6/

You just gotta search for it on this website, I have the V8 so it will be a little bit easier for me. I have to work on the drivers side and that side is a little harder than the passengers. I just bought my coil at oriely's paid 45 bucks and it comes with a life time warranty. Im about to start on it soon i gotta kick my roommate and his :q:q:q:qty cadillac outta the garage first. Wish me luck everyone hope this goes smoothly....:(
 
For sure your gonna need a 7mm box wrench to get the bolt out by the brake booster. Other than using that wrench and moving it about 3mm at a time i couldnt find another way to get it off, all the rest is easy stuff.

If there is oil on even that one, you need to change your valve cover gasket or you'll be in there again in a month doing the same thing.

Any parts not made by FoMoCo or not displaying the Motorcraft brand name are technically "aftermarket."
Autozone gave me a Duralast coil because that's what they had in stock. It'll probably die in a year, but by then hopefully those HD coils from the other thread will be available.
Tell your roommate to push that Cadillac over a cliff, it will save him many headaches. :P

Yeah tell me about it, he keeps having problem after problem. He's in denial that it's a pos. It rattles so bad when his system bumps it's terrible. I don't know why he won't ditch it. He wants to fix her all up its a 1987 cadi deville so ugly. Oh well his waste, that's probably why he keeps hating on my LS. But anyways i finally got her all fixed. The coil i had bought from Oriely's was a BWD coil. I would of gotten it done quicker but i had to go save a friend from gettin arrested....long story. My biggest pain in the ass was trying to reach those dame 7mm nuts. I ended up loosing one somewhere so i only have 5 of them on there nice and tight. Shouldn't be that big of a deal missing one, the one by the break booster. The good news is i didn't see any traces of oil down there at all, and the sparkplugs looked fine. The bad news was I kept dropping my wrench getting it trapped in the engine bay too many times i lost count. I disconnected the negative terminal on the battery to reset the ECU. My hands are a little cut up but i got the job done. Saved me a lot of money at the expense of all the patience i had left. Now she sounds alive again and the check engine light is off. Only ended up costing me 45 bucks. I do really reccomend doing it yourself, why have the dealerships rape you. Hopefully i have no more problems regarding my coils atleast until the HD ones are available. Thanks for all of the help guys and my kudos to this forum and the write up Quick wrote for coil replacements i really appreciate that it.....:headbang: :headbang:
 
My hands were all beat up too. I actually tied a string around my 7mm wrench because i knew i'd be dropping it and didnt want to go hunting for it. I also left the one bolt off by the brake booster.
