The fuel filter has never been changed on this vehicle. Would that cause a rough idle ?
no, one code is for the secondary air and the other is an evap code.

Just to add to this one the 2000-2002 single cam S models are known for the number one intake port leaking where the intake meets the head.I have replaced tons of intake manifold gaskets on those gaskets leaking.They wrinkled the gasket when installing them at the factory.For the P0442 I would make sure that both vacuum lines are on the canister purge solenoid under the intake manifold.The common reason for the p0410 code is a bad combonation valve.I would also replace the fuel filter they should be changed every 100,000 miles by now its pretty clogged up.
