My car has 223000 miles.
My car has an automatic transmission.

Since the vehicle is over 25 years old and with over 220,000 miles the engine and vehicle may have more than one problem. If your engine is only having the problems when you get it warmed up then you have a problem with something that changes when your engine heats up. I suspect you are having problems with the ignition and fuel system. You may have low fuel pressure or low fuel flow like a clogged fuel system or filter. I suggest having a mechanic, like one from YourMechanic, come and do a complete diagnosis for your engine misfiring and quote any repairs needed.
