With regaurds to your codes--Po172-system too rich bank 1---I would surmise you have a vacuum leak big time -need to check all of your vacuum hoses-if they haven't been replaced since you have owned the car now would be the time to do so
. Next -P0410--secondary air malfunction--there is a vacuum hose that goes over the top of the engine and hooks to a vacuum solinoid that operates the secondary air motor on start up of the car when the cars, cold-could be a leak in that hose--or it could be the solinoid it's hooked to (over on the passenger side of the car)that part wears out about the mileage you have--if not those two you will probally have a bad air injection motor-expensive little bugger unless you can cop one off a juncked car,
Hope that helps
