I just bought one for my 97, and it turns out its not the pump, so if you want I have one I would be willing to sell you for $200 shipped. Guaranteed against DOA. It was tested 2 hours ago... unfortunately didn't fix my problem (see my other post). I'm assuming either the vacum hose maybe popped off, or maybe the valve. So annoying because apparantly it's 4 hours labor to pull the intake off to get to the hose (plus the time to put it all back together) - if anyone has info on this let me know! I'm going to try to get some info and tackle it myself to save some coin.
Not a real big deal to replace the air pump though from what I understand, I'm going to pick the car up in an hour, I'll let you know what they bill me. They were guessing 1-1.5 hours. You can access it from the top of the engine I'm pretty sure, 3 screws and 2 hoses to disconnect. I was going to do it myself originally but don't have the diagnositc tool to reset the engine light and codes to see if it's fixed.
