It could be one of three thiings worst first. Cat. converter is bad $400 to $1000. Sensor or sensors are bad $40 to $150 each. Air leaking into exhaust when hot prior to converter. Big Doubt here! Engine exhaust pushes out not in! It's being read on Bank (2) sensors If it were reading on Bank (1) it would Be PO420.
If sensors are High Mileage Over a 100K they probably are bad but should be scanned before spending money on something that isn't going to help.
If you have a V type motor and your getting 420 and 430 it's more then likely the converter.
If your in a state that has emmision checks grab your wallet if not this light don't come on thill it's at about 96% which means your still not polluting that bad. Also a miss firing cylinder can sometimes trip this code.
To me it sounds like your ride needs some TLC! Hope this helps

GM OBD 1
Catalytic converter efficiency failure, bank two. That would be the passenger side.
OBD-1. 1995 was a changeover year. All 1995 cars/trucks (GM to my knowledge, I don't know about the other brands) were OBD-1 and some have an OBD-2 connector, but still are OBD-1.
The paper clip trick was a OBD I GM thing. For your 97 Ford you need a code reader for OBD II.
WA is the paint code for Artic white.
you need to recalabrate with a tech 2 at gm dealer Or you will have to replace the failed cam sensor.
The OBD2 plug for most GM vehicles is to the left or right of the steering column, at the bottom of the dashboard.
Map circuit low input is your answer.

You can usually borrow, rent or buy a GM OBD code scanner at most auto parts retailers. Since OBD2 has come out, the old version has been called "OBD1", but that's not what it was called when it was being used. The 1995 Eighty-Eight is a crossbreed. It uses the OBD-II connector but it is an OBD-I system. It appears that OBD-II code readers can handle this but I'm not positive.
If you mean a GM vehicle that was built during the transition from OBD1 to OBD2, the answer is if it has a OBD port a scanner will work. GM MDI Tech 3 Interface is Dealer Level Diagnostic Tool for Multiple Brand vehicle: GM, Opel, Chevrolet, Saab from vipprogrammer.com
O2 sensor CKT slow response (bank 1 sensor 1). Sounds like a tired B1S1 O2 sensor if all the connections are good.
