96 Olds Achieva Surges or stall when cold

I have a 96 Olds Achieva with the 4 cylinder that will stall or run rough when engine is cold. If you start the engine and let it run for a few minutes, it's usually ok. You can also get around the problem if you step on the gas and hold it. The check engine light does not come on. Any idea's?

Get the ecm scanned for stored codes. You could have either an EGR valve or an air bypass valve problem. But this is just suggestions. There is no way we can diagnose this problem with the limited info provided.
