Do you have a shop manual? I have one and I will look it up this evening. If you dont have a shop manual get one. It is well worth the investment. They sell on ebay for considerably less than what you can buy them for at a supplier. I paid $20 for mine.

the purge solenoid is the same as the EGR solenoid (the EGR solenoid just has a vac adapter thing on it) If you have a scannre you can see if the system is activating the purge solenoid (which happens @ part throttle during closed loop oepration if I remember correctly) from the canister purge field..it's a simple on/off switch.
