I don't remember the specifics for this car but you'll want to search for an
"electrical load idle booster". Perhaps Google will turn up something or
someone here can offer more specific advice. If not, then a factory service
manual from http://www.helminc.com ought to cover it. These manuals seem a
little pricey at first but are a good investment if you plan on keeping your car
for a while.
