Hello, here is a thread I found on this site with from what it looks like, the same problem(with an added solution) that you have. http://www.fixya.com/cars/t1576683-1999_cougar_diagnostic_code_p0430_p0420

replace throttle body gasket. first check to see if carbon has built up around the throttle valves in throttle body if so remove and clean it with throttle body cleaner.and a old tooth brush. besure to remove all electrical components or any thing that plastic or rubber the cleaner will destroy it.
SOURCE: battery light stays on
Your alternator isn't putting 14 volts out to the battery. Check the stator wire on the alternator and the 3 wire plug make sure there is no gap on any of the alternator connectors and they are on VERY firm!
Hook up a multimeter inside your car and watch the battery voltage! if under 14volt you got an alternator problem!
