I am having a weird issue with my car. I have owned 3 COP setups, 1 brand new Spoolin up, and 2 used ones.

My car seems to like it for a couple weeks then it just wont start at all, I throw my stock ignition coils back in and it starts right up.

Fuse has been swapped out for a 15 amp.

 

Dont add a bigger fuse then what it is designed for.

have you done a spark test when it decides to quit?

 

The fuse that ships with the Spoolin up kit and the STM kit are larger than the factory fuse.

 

Stock coils are better.

 

Whys that? I had never ending ignition issues with the stock coils.

 

Stock coils are not better, anything above 450+ shows benefits of a coil on plug setup.

 

That's true if you mean better than none at all.
or if standard.
