Already changed purge on the car, code po452 still comes up
Po452 indicates an issue with the nvld valve. it is located above the fuel tank, in order to test this you will need a hand vaccum pump, and and a multimeter if you look at the canister there will be a standard vaccum line and a vent tube wich will be larger, the vent tube needs to be blocked off, and the vaccum pump will need to be hooked up to the vaccum line. Next the meter will need to be inserted into the harness coming from the switch (orange wire).(''t''pins from wal mart sewing department may be helpful here). Keep the harness hooked up key on engine off, when vaccum is applied (about 1 hg on the gauge) the voltage should start at 12 volts and drop to 0 volts if operating correctly ,test it several times, the most common fix is to replace the whole assembly, it includes the charcoal canister, and requires removal of the fuel tank, hope this helps chris.

Check the input shaft and output shaft speed sensors on the transmission. One is likely bad.

P0505: Idle Air Control System
There is a small motor that controls the amount of air the engine gets when you aren't using the throttle. The computer uses this small motor to control your idle. It sounds like it needs to be replaced. You can try cleaning it first with some throttle body & air intake cleaner.
