1994 Acura Vigor Two Wheel Drive Automatic 171000 miles

Hi. I have a 1994 Acura Vigor with 171,000 miles on it. Up until last week it was running fine. Now it still runs good and strong while it is cold. But 10 min. In to the drive when the engine warms up it starts to shake and I guess it misfires and seems like its going to stall at the traffic light. It feels that the car looses power when it warms up. The missfiring/shaking gets little better at 3500 rpms, but never goes away. I changed the spark plugs, but that didn't help.
Any ideas what shoul I do next?

Might have an injector sticking. Did you replace the fuel filter as well? You could try some injector cleaner or have a shop run some through for you, might help. Otherwise you will need to measure the resistance across the injectors when warm to see if any one is out of range, or have a shop check the injector wave pattern to see if one is bad
