Default ECM?

I am having lots of problems with my vette. I don't know if the ECM is the problem or if it is electrical connections. How do I tell if it is the ECM?
The idle speed picks up as the car gets warmer. I have checked the timing and it is fine. Could this be yet another EGR problem?
HELP!!! :confused:

You could have a sticking Idle Air Valve (IAC)...And also yeah,egr could have issues also. Unplug the IAC when it starts to do that and see if it goes away,or changes for the better.
