If you know someone with a good scantool you should be able to see what the problem is. You may want to do a compression test, but if it runs slow at low load OK it's probably OK.

Test by: disconnect battery, remove the upper O2 sensor, reconnect battery. If the car performs better, then you know the pre-cat is clogged. If car doesn't perform better, try with lower O2 sensor. If the car performs better, then the main cat is clogged.
