Q: Car will hesitate going up hills. Speed will decrease, but going straight it will do fine. I wanna fix this asap.
We go up a hill the car will go from 35 to 15 in a second. When the car goes straight it. Works perfect. And sometimes when your not even on a hill it will stay at 25 mph doesnt matter how hard you hit the gas will not move beyond that point. What could the problem be? The spark plugs? I check my oil every week, everything is fine. Changed my coolant sensor, fuel filter, nothing works.
My car has an automatic transmission.
