alternator??

What is the CEL code? Number to be exact.

When the engine is completely cold does it start and run ok?

Also check all the plugs and plug wires, I have seen cars start and run good when cold and warm up fine, then after shut down and allowed to cool a little will have trouble running from a cracked procelin on a plug electrode. Just a though. Let us know what you find.
