P0401... again. Damn EGR

I got a CEL a while back (P0401), and replacaed the EGR solenoid thingy. Since I was sick, I didn't drive too much, so the car just sat there for about 2 weeks. Well today while I was driving, the CEL came on again, and the same symtoms came up. Looks like I'm going to have to buy an EGR valve now. How much do these normally run? I have to replace the EGR valve on my Olds... (it failed emmissions... actually, it died on the dyno), and autozone wants $130 for that one. Looks like I'm going to be doing 2 EGR valves this week. I don't want to though.

I dont know if the 4g63 N/A EGR will fit on your 420a. But if it will, I'll send you one of my spares. Just pay shipping..

Naw, it won't fit. Wish it did though. Great price. Thanks anyways.
