Why is service engine light on after driving up the hill?

(1999 Pontiac Grand Am)
I added fuel then drove up a steep hill, at the top of the hill the car jerked briefly & service engine light flashed for couple seconds and then just sstays on. Car seems to have no driving issue. I replaced new cap, no success.

Sounds like a slight engine misfire and the light came on. I would take the car to a shop and have the computer fault codes scanned.

Auto Zone pulled code P0300 and P0463, added Lucas upper cylinder lubricant and injector cleaner, drove so far 25 miles, no success.
