94 Jimmy EGR Valve, Code 32, please help ASAP!

Alright, I have a 94 Jimmy with the 4.3L CPI engine code W. I was having the problems relating to EGR Valve needing cleaning, and CPI problems. I had my EGR Valve, and entire fuel system cleaned out about 2 weeks ago, than I realized that my CPI and Nut Kit was leaking, so a couple days ago I had the CPI & Nut Kit replaced. Now all of a sudden today while driving, after about 20 minutes, my check engine light came on. When I shut it off and started the vehicle back up about 3 hours later when I started the vehicle up, the SES lightwas off, than about 20 minutes it came back on. I went by Autozone and had the code tested, and its Code 32, which I know means EGR Failure and I am experiencing the EGR symptoms again. Should I have the ERG Valve cleaned again, or replace since it was just cleaned out along with the entire fuel system about 2 weeks ago. Someone please help, because I really can't afford to replace the EGR do to the expensense, however if it needs it, and cleaning it wont do no good, I will do so, but I don't want to go through the time of cleaning it, or paying $30 to have it done, if I'm going to have to replace it.

Decided to reset the computer and see if it was possibly just an old code. Sure enough thats what it turned out to be was an old code, after resetting the comptuer and running the truck to the same place as I did when it came on, its only reading code 12 now for no problem. The rough idle and seemed like missing, which I thought was the EGR possibly missing up just turned out to be a loose plug wire, so everythings good.
