You can do some searches on the code numbers and on 'AIR system'.
But, I would start with cleaning the grounds in the engine bay and just making sure the all the tubes are connected. The tubing starts out at the air cleaner (the only small tube coming off the air cleaner) and it goes to the pump under the head light. Then it goes to a tee near the brake booster, from the tee it goes to each exahust manifold. There is a valve in each of these lines, right next to the manifold on the drivers side and behind the drivers side cylinder head for the pass side. The tubes become metal tubing after the valves to handle the heat from the exahust manifold.
Take a look at the electrical sticky at the top of the forum for instructions on the grounds.
After that, if you still have issues the next thing would be to try and lubricate the valves in the system. Open the rubber tube near the valve on the drivers side, its the metal tube that comes off of the exahust manifold. Spray wd40 on both the inside of the valve and into the tube, as there is another valve behind the cylinder head. Fog it and it should get some...
Its not a huge problem, and I have not seen much reported about actual failure of the parts. Usually stick valves or grounds that need cleaning. The AIR system is only used in the first a couple of minutes after start up.
