Q: Car Hesitation Acceration

asked by on August 11, 2016

When I'm driving my car, and it is driven for a while, and is in the normal operating temperature. It runs normal, but after I shut it off, and come back and when the engine is still warm it hesitates to get up to speed. But when I continue to drive it the hesitation goes away, and performs normally during everyday driving. Also what I discovered when I go up a hill when the engine is hesitating is that it wants to stall, and there's no power when I push the gas pedal down. Secondly I heard some backfiring from the exhaust when the car is trying to go up hill. Lastly when the car is cold it performs normal, there's no hesitation or problems as detailed above. Thanks

My car has 216745 miles.
My car has an automatic transmission.
