I don't know, but you may want to check the wiring harnesses under the hood. If you have any wires that are cracked or the insulation is broken or brittle, they need to replaced (better yet have ford check them under a recall they issued a while ago). This seems to be a problem with 95 models and ford will replace all the engine wiring harnesses for free under their recall, as long as you have less than 100k miles on your car. Infact my 95 Mystique is at the dealer right now getting the engine wiring harnesses replaced. I noticed with mine that my electrical power would fluctuate slightly when i took my foot off the gas, however there is no prescribed symptoms for failure of the wiring harnesses. When you have stripped or partially stripped wires exposed to other striped wires, anything could happen.
hope that helps,
good-luck
NOTE: You must ask specifically to have the wiring harness recall checked (recall # 99M03). They do not normally check it when you bring your car in. They only check and replace it if you complain about it - their lazy. This is what I had to do just a few days ago.
