Engine Code Problem

Was wondering if anyone can help me figure out what the engine code "auxiliary emissions contol" means? What needs to get fixed to clear this code? Its a 96' v6 coupe. She runs just fine and I've cleared the code several times but it keeps coming back. Any help would be appreciated.

Do you have the number for the code?

It is a P1406-"Auxiliary Emissions Control" punch into the software and an "EGR pintal circut" comes up. Not too sure what a pintal circut is. Should I just try replacing EGR? Is this a common thing? Thanks in advance for any advice.

hmm do what i did on my other car:) get black tape, cover the CEL xD no, seriously i did..cuz it was an annoying prob and i didnt know what was wrong w. it. turned out it was overheating..but thats another story :P

The CEL bulb has been pulled out, in my toolbox, for a few years now. I just read periodically w/ code reader to see how she's doing. $135 for new EGR. Don't quite want to do that yet, gonna try to push the old ones buttons first. Just nailed a cyl. 4 misfire to the coilpack last week.
