Hesitation/stumble during warmup

This is far from a show stopper of a problem. Just an annoyance.
My 96 GC 3.8 with 188K miles has an ever so slight hesitation when you step on the gas the first few minutes it's running for the day. Otherwise, it runs just fine. Been doing this forever. I really don't want to tear it apart for something this minor. Just wandering if anybody has experienced this and if there is a simple fix.
And oh by the way HeadlessHorseman - that's 188K miles with the original transmission still going strong.

Simple answer-
injector cleaner in a bottle.
Long answer-
clean plenum/injectors/plenum and replace TPS
when it rains, it pours....:bricks1:

Oh yeah, one other stupid thing.... did they switch your gasoline over to 10% Ethanol (they did here in VA)? that could make the engine hesitate a little...

Yes , those are options but, I think I'll wait for it to get worse. Then again I've been waiting 8-10 years. Not sure about the ethanol but it was hesitating long before ethanol was around in California. Isn't a quick learn more transmission related than engine related? Pretty sure this is the engine doing it. Spose it wouldn't hurt anything though. I appreciate your suggestions. Cheers!

I have a 95 Caravan 3.3l which began to stutter and hesitate on light throttle applications. No codes but I found that a cracked vacuum line was the cause. The hose was attached to the EGR. If you have a vacuum gauge connect it to the intake and start the engine. Pinch or plug as many vacuum lines as you can one at a time until you see an increase in vacuum pressure. My engine would wistle every time I lightly touched the throttle. Then go away under acceleration. Changing gears from drive to reverse would cause the engine to hesitate. The vacuum leak was causing a lean condition in the engine.
