I have a 97 accord non vtech 2.2 4...has 119,000 miles. Seems to run well but after it has been at expressway speeds for 45 minutes...to 2 hours...it picks up a miss...check engine light flashes...let the car cool down...all good and it goes away. I has new plugs and looks like wires and cap...any ideas?

 

See what codes are presented and post them, hopefully more than just P0300-0304 (missing cylinders).

good luck
