I've have a Chilton ford 94-98 mustang repair manual and code p0354 says Ignition coil primary circuit fault. Whatever that means. Hope this helps.

Looking through the codes I don't see any other ignition related codes. I would think it would be a coil pack. Not sure though. Maybe someone else will chime in.

I believe you have 2 coil packs instead of 8 individual coils( coil over plug style).. Call your local autozone or advance auto, they have a machine that might be able to test it.. I would bring the ignition module and or control module too.. Now if these test good and were tested correctly, it can be a cam or crank sensor.. Not sure which ones control the fuel injection and ignition signal.. Your coil needs a signal to know when and what cylinder to send the eletric charge to, same concept with your fuel injectors..

I never had to replace a coil in my 98, so not sure what a good price would be. 52 each sounds like a decent price.

Never heard of it, but I looked it up. It seems to be some sort of peak performance enhancer. Meaning when u stomp on it, it sopposed to add more HP by reading air and fuel ratio or something like that. Sounds like a fluke. it says it has an off switch. Do you feel any difference when ur racing? Maybe try it when its off and then turn it back on and see if there's a difference.

That's because the Idiots and the franchise can't trust them with a ohms meter lol trust me they can be tested, search the net and test it yourself.. If a ford tech can test them ( all components I mentioned earlier) then it can be done.. Honest without a misfire code it sounds like crank/cam sensors.. Another question.. Was it moist or damp outside when your car check engine light come on? Did it run ruff (lack a power or a misfire).. Visually inspect coils for any cracks or signs of moister, even hairline cracks will allow water in that will cuz a fault in the coil... Let me know.. I can walk you through the test if you have an ohms/volt meter.. Don't start throwing parts at it, I'll Save ya some doe with process of elimination.. Any other codes?

Have you tried something as simple as disconnecting each wire and reconnecting them to the coils to make sure they are getting good connection. Sometimes you just have to do that to re-establish a better connection. Kind of like cleaning your battery terminals every once and a while. Just another cheap check.

Re: CODE P0354

RedStang they can test the coil packs if you get somone that knows what they are doing and have the volt meter along with the book. I know, cuz I used to work at Autozone and I tested them like yours. You cant test the Coil over plugs that come on 99 and above well not at autozone anyways, but if you are handy with a volt meter and now the specs of what the coil pack should be then you can test yourself.

The thing in the picture is what Silver said, but it wont cause that light trust me I took them off my car and no issues because I got tired of them being in my way when I put my valve covers on and etc. How many miles are on the car? If it has over 120, 000 thousand just replace both. But here is what I found, might not be right but its more information to put you a certain area.

P0354 code is related to coil D or cyn 4 so find cyn 4 and trace the wire back to the coil pack and replace it. Once you replace the coil have the code erased. If this does not fix the problem then swap the coil packs from one side to another, erase the code, then see if the code stays gone.

Here is another thing you can do before you buy anything to see if it is coil related. Swap your old coils from one side to another( example: take the driver side coil and move it to the pass coil) but remember where the wires plug in, make a diagram of your own numbering which CYN goes where on the coil. After thing this and the problem goes from this code to another code then its a coil, if it doesnt and the code still stays the same then its not related to the coils but yet something that tells the coil packs to fire (timing). When you swap them they may or may not mount up right but you can figure a temp way of keeping them there to see if the code goes or goes away. But once you do the swap you will have to clear the code out but a reader or disconnecting the battery for like 5 mins I think.

If im correct the cam sensor is the one that tells when to fire and put fuel in there and the crank is the one that tells the computer which stroke it is on ( exhaust, intake etc). Most of the time if these go bad you will have a code for them, MOST OF THE TIME! If the crank and cam sensors were on the way out of going bad then you will have a delayed start or a no start which SOMETIMES doesnt cut the light on.

Re: CODE P0354

I want to say cyn 4 is on the pass side the very last one.....well you can check the ohms on your coil pack but I dont know the specs....you might be able to google it.

Re: CODE P0354

Chances are it will fix it but you just have do what I mentioned above to see if one of the coil packs are bad.
