That’s very frustrating. Funny part is is that my old one is also an MSD and it looks like it’s seen far better days yet still works better than a brand new one. Oh well. Now all that’s left to do is figure out the coolant burning issue and the super loud pops out of my exhaust when decelerating/engine breaking after a hard pullIt seems like every 3rd or 5th MSD cap I come across is crap. No idea what the story is there. I have them on my cars too.
