07 TrailblazerSS 2WD
I recently had to change out the ECM on my SS , it has the same tune installed on it as the old one did. I had a case relearn, and VATS done so it would work properly. The issue that I'm having now is that it is stalling on me when i slow down and the idle drops below 700 rpms. If i come to a complete stop the idle will drop to 400 and then recover back to 700 . anyone have any idea what is happening?
