OK I know my ignitions pretty well, but I aint too proud to ask for help.
My dad always said someone who knows something well knows when to ask questions.
I thought yall might have a shortcut through the troubleshooting.
I have not yet replaced the cap, rotor, plugs, wires, coil, module, or distributor yet.
the car runs GREAT under light load at normal driving speeds.
I set the timing to the final position today and its smooth as it can be and gets to speed with a purpose.
only one issue right at about 3200-3500 RPM underload (accellerating or hitting passing gear):
a miss of some kind and when I get back below 3200 or so I can get on it all I want untill it goes back up to 3200 or so.
this is confusing to me, it doesnt miss under load at a powerbrake, or anywhere under 3200 RPMs.
I thought there might be a Mustang specific issue to explain this.
I was thinking I needed a stronger spring ratio for the mechanical advance, because it was hitting full advance too soon, only to find out there is no mechanical advance.
I dont have the time to troubleshoot it today, and since I just got out of surgery a few days ago, its prolly not a good idea anyway.
My best guess is the module or distributor....
Any suggestions Y'all?
Thanks
