I've been dealing with a similar issue off and on for years with my Duster. I can get the car to run right for weeks at a time, and then a high-end miss comes back. I change one component, it runs fine for weeks, then the miss comes back. Change something different, it pretends like it's fixed, and then the miss returns. It seems to me like it is somehow heat related, as it tends to start breaking up above 5,000 rpm only after making a couple of passes in succession.

I've been through alternator, ignition box, voltage regulator, switches, battery, fuel pump, fuel filter, fuel pressure regulator, distributor... the most aggravating thing is that it won't just stay broke or stay fixed!

Another odd thing with the car is that ever since moving the battery back up front, the voltmeter has been reading very high: 14-16, even with a fully charged battery, and trying different alternators and voltage regulators. Could this be frying something else in the system?

Mike Raddish -- think that the ballast resistor could be *bad*?
