Hello,
I am having an electrical problem with my 78 Mustang II, 302 V8. Some have said it is Surging, but really it is a high speed miss. I have original ford shop manuals but I can not test the secondary system because the manual calls for a "scope" and I don't have one. I was hoping someone knew another way to test the secondary system of the ignition without using a "scope" OR could tell me a possible solution to my problem.

Thanks, Mike

I would think surging would be ignition timing or a carb problem.
I assume that you have already checked the basics, like a plug check and a simple "lift the hood" in the dark of night and look for the multicolored lights. Replace the coil and give it a try.
I know the above isn't any help but I thought sombody should say something.

Later

Welcome, Mike.

Did you check the vacuum advance? I had a '75 Ranchero that had the diaphragm go. An internal vacuum leak will occur along with the lack of advance could be the problem.

I have done everything. I was hoping anyone has had a similar problem and knew their solution.

Thanks, Mike
