I have brand new coil packs on my sc 98 cobra and I'm thinking that's the reason why it misses and sputters like crazy any ideas guys?
do msd coil packs fail ?????

All of them can fail, but the stockers fail much less often. The MSDs add no power and they fail the most often.
Well was it doing it Before the MSD install?, if it wasnt then theres your problem. Fastest way to tell is plug into the OBD2 and see if theres a code for it. mabye you didnt put the right spark plug wires to the correct spark plugs
where are you getting that info from??? Ya MSDs fail all the time thats why everyone buys them when making aperformance car,
MSD's make the plug burn hotter which burns the fuel more completely adding a small amount of hp plus there cheeper then those over priced oem ones

It doesnt make the plug burn more hot it creates a stronger spark, to ignite the air fuel mixture.... And its been proven that msd modular stuff sucks, ford oem is by far the best you can buy as far as reliability and as far as performance there is no gains to be had with aftermarket coil packs.
I don't know what y'all are talking about....3 years strong baby! An counting.
I installed those on my car and had nothing but problems. The car was always breaking up at WOT, ditched them for the stock units and car ran perfect
Having a plug with a shorter cone will burn hotter, the coil pack just sends a higher voltage
Msd coil packs fail all the time. Its a myth people "buy" them for performance cars. If you look at a lot of the high horsepower coil pack cars/build threads they ditch the crappy aftermarket ones for oems. Why? Because they have issues. I have a set of msds on my n/a build and had issues with breaking up I assumed were due to lack of tune. Once I switched to oems just for giggles it no longer breaks up.
Some people get lucky tho and get a good batch of msds, but for the most part Iwould avoid them like the plague.
Msd ignition boxes on the other hand are a whole different story.

My car when I step on it completly falls on its face can that be the msds??
Could be. If you've got a set of stockers throw them on and find out. Either way it will probably improve somewhat.
I just whant to know if that is cause for my car running like shit it when I go wot it just falls on its face
I don't have the stock ones :/ I much rather borrow them off someone car just to see if that fixes my problem
I had the same problem. Ditched the msd and car ran like a beast
If I were building another big block carbed car then yes,
MSD 6 or 7al and blaster coil, dist, etc.....
For these cars the MSD modular parts tend to be crap and the stock coils have plenty enough voltage for almost any build out there.

I have two stock ones that are known to be good. You pay shipping and they're yours.
Ironically I trashed my MSD coil packs less then a week ago because my car started to run like crap and threw a CEL light for bad coils. I put my stockers on amd now I have no issues.
+1
Had my msd dis-4 12 years it just died last month because of my own fault.
I also use their wires for the last 8-9 years and no problems there either.
It seems their products get bashed all the time.
I have my stock coil packs on the car. 14 years old. 45k. I would use the stockers if mine failed.

I've had my msd coil packs for over two years now.. Car still runs great, actually when I replaced them it seemed like the car would start stronger. I replaced the originals when they had 115K miles on them.
I hardly see anyone ever trash on MSD's products except for the modular coil packs. The DIS-4 and similar are great.
