Chrysler Repair: 2005 Dodge Caravan 3.3 egr problem, powertrain control module, 2005 dodge caravan

Question
I have a 2005 Dodge Caravan 3.3 engine, 120,00 MILES, the engine light was on and the engine was sputtering, all answers pointed to the egr valve, since it was easy to get to I changed it myself, after one day of running smooth , maybe 25 miles, it started sputtering again and the engine light came back on. I check my bolts and all were tight, I checked and cleaned the electrical connector. The only thing I didn't change was the round rubber gasket on the end of the tube that attaches to the top of the engine. Could that be the problem now? Or should I check for something else. I did blow through the tube and it seemed ok. Thanks for your time.

Answer
if the seal isn't leaking i would say its not that.Are you sure its a egr code and not something like this tsbDaimlerChrysler Corporation.
