To the original poster:
Obviously something is amiss in your electrical system, to be burning through ballast's. I would go through the ignition system components, and see if I could figure out the problem. It could easily be a wiring problem as well. Have a new ecu, coil, ballast on hand. I also wouldn't fall for the gm end all be all bs. No cheby parts will ever touch my Mopars, period. Chrysler designed one of the finest ignition systems, with millions upon millions of proven miles.
