start up prob
Reflashed the ECM or swapped the unit for a Camaro part?
CEL shouldn't come on without a code. If it does, something is wrong with your wiring or ECM. Check pending and memory codes.
Does it do this every start? Its normal to have trouble with idle on the first fire after hooking up power. The ECM needs time to do an idle learn. If it doesn't go away, then you have a problem.
I'd start by checking for vacuum leaks and post-MAF intake leaks.
