I have another "simple" thing to try.....as I would hate to see you replace parts to end up finding out that is what Modtech mentioned...or this.....

Make sure that you have your gas cap on correctly....and most locking caps do not seal correctly as many people who live in emission testing areas have found out. I would eliminate these before checking further.

Another thing to check would be to make sure that the vaccum lines are good.....I seem to remember that the purge solonoid (this is what takes the electrical signal from the PCM...and converts it to a vaccum signal) is located on the firewall.....driver's side of the car. The solonoid that is located near there.....on the back of the upper intake manifold....is the EGR vaccum solonoid. The vaccum source for both.....is the PCV line. I would imagine that the lines TO the solonoid are not leaking....as one would expect that you would have additional code(s)....like EGR. However....after the solonoid between the solonoid and the charcoal canister (under car.....inside frame member near fuel filter) is possible.....or a kinked line......
