You probably have a bad catalytic converter, but it is possible the ignition timing is too advanced. If the timing is correct you could try and cheat your way through the test by retarding the timing. This would be done by turning the distributor a little clockwise, lets say...8 degrees with a timing light.
Just don't tell Al Gore.

1996 jimmy failed an emission test


Did you change the air filter. The fuel filter will have no impact on emmision's but the air filter is a very common problem.If you usually drive it at low rev.'s then before you send it for emmisions test you will need to put it in a low gear and floor it for about a mile the reason is when it is being tested the engine is reved up to around 3500 rpm and any build up of unburned fuel or oil in the exhaust system will put up the emmisions reading.

The N0x to high


Start with the cheapest part first, new air filter, o2 sensor, egr valve, then if the problem still persists, consider a new catalytic converter. Probably around $125.00 to $160.00 at a reputable shop other than a dealer who could charge double!
