I don't have a lot of faith in msd products. I'd test it. Take the box out and put it back to factory ignition. See if it fixes the problem. You probably don't need it anyway.

I was thinking putting it into the passenger side area on the floor and driving it that way for 30+ minutes to see if the problem happens again? What do you think about the MSD coil?

Coil could be an issue if it has problems when it's warm. I'd test it when it's warm and the engine isn't functioning correctly https://www.aa1car.com/library/ignition_coils.htm
I'd still just remove the msd box. Honestly the most likely culprit and pretty unnecessary.

If you have positive info, that would be great. How can I fix the problem. Make steps to fix the issue, stop saying things are unnecessary.
I really dont understand your help?

What is unnecessary? The 400$ MSD Digital 6+? I should take this and throw it in the trash?

If you don't like my advice then I'll gladly not reply. I'm not sure what you don't understand and I don't read anything I said as unnecessary. Good luck, I will not be looking at this thread again.

Re: Could MSD ignition location be causing my misfires?
I don't see how I was giving negative info. Test your coil when hot. Remove the msd box, see if the problem goes away. The stock type ignition system is plenty to handle your configuration. At no point in time did I say throw it away but they are problematic, and the symptoms point at that box. If the problem doesn't go away without the box you can put it back in if you like.

Re: Could MSD ignition location be causing my misfires?
Why so angry? He gave sound and logical advice. Then another member just gave you the same advice. Are you going to yell at him too? The logical thing to do is to revert temporarily to stock ignition to see if your problem exists with no modifications. Or go ahead and buy another MSD box and plug that in. Maybe that will fix it, maybe not. Don't rip people trying to help you from 500 miles away. We can only give advice. Reactions like yours are the reason you get so many stupid *** answers when people who have the experience and knowledge just give up.

I am not angry, I am tired of replies where people reverse my question back into the form of an answer without saying anything helpful.
Example: "Should I move my ignition to a different spot, maybe its overheating"? Answer: "You should remove your ignition, its useless"
Your reply is also unhelpful and is just complete trolling.

Re: Could MSD ignition location be causing my misfires?
So let me get this straight. You come on asking for help. Several people reply almost the same thing. You get mad and call them trolls. You say RIGHT IN YOUR FIRST POST "It is a digital 6plus and now that he mentions it, the problem only started when I installed this thing....in 2004."
How is anyone but you a troll? Take the box back out of the circuit and see if it runs better on the stock ignition. I have had defective MSD parts out of the box. You have been ignoring this problem for 18 years. If you won't take the free, yet helpful, advice some good people are giving you, go back to your cave.

I asked you to stop, and here you are. Please stop posting in my thread, just go bother someone else.
Thanks.
