Q: Slight misfire while cruising

asked by on June 15, 2016

While cruising when the engine is hot, I am getting a very slight misfire. This occurs more frequently the hotter the day is. The sound is almost a "poof" and you can feel a very light push back on the gas pedal. No check engine light has come on. I have changed the spark plugs and that didn't seem to help. What would be the next place I should start.

My car has 81000 miles.
My car has an automatic transmission.
