don't forget about swapped wires...are you having an intermittent miss, or a steady engine sychronous miss?
the starter or alternator shouldn't have anything to do with a miss unless you're not getting enough volts to your ignition system.

This was happening on my 92 im foing the motor swap on now... Its hard to explain but i will try. under norm driving trhe car was ok but under acceleration, the car would feel like it was hitting a rv limiter but the r's were still going and i was only at like 4500. It was like having a bad spark plug. but i replaced the plugs. It was like little glitches in the acceleration, little pauses or hesitaions. I felt more pwer wanting to come through but like something was not letting it...
are you asking what can cause a misfire or what having a bad alt or starter shows symptoms of?
The starter has nothing to do with it, and unless the charging system is toast (read will not allow the car to start), the charging system should not have much effect. That is one reason the puter uses a 5 volt reference voltage instead of battery voltage.
One can do a cylinder balance test to see if injectors are firing decently.
Good luck.

"Wind up like a fan" do you mean faster? Sounds like you have some compression issues. Especially if it cranks over extremely easy. Another cause of a miss is excessive carbon deposites. Usually caused by excessive blowby. When carbon forms in excess, it will absorbe enough fuel to create a lean condition. But more so the blowby (oil in the combustion chamber) will lower the octaine rating of the fuel and cause a missfire.

Maybe if the wire has an open and is near an alternator. Or starter lol. It might ground to it but that is a wire problem. One could argue EMI but I don't see it happen. Plug wires are thick.
Yea i was having alot of problems with that cars setup. Im in the process of putting ym new motor in you can follw it http://forums.stangnet.com/showthread.php?p=5189898#post5189898
and help me along. Hopefully after i re loom all the wires and detail everything i can limit an open end somewhere. I would lean tward the motor having the problem itsself. IDK why, i had some major issues with it. My other motor never did that. Im repalcing the plugs and wires and cap and the plug that got mutilated in the fire and i have a new starter to so hopefully it elims the problem. Thanks guys, if you have anymore suggestions to help me along please go to my other thread on my build up!
