Q: Car randomly feels like it loses power and jumps

asked by on

When I am starting up from a stopped position or accelerating forward, my car feels like it is losing power. It only happens for a second, but it slightly jumps and then returns to normal.

Hello there. Many different items can cause a lack of power intermittently such as this. The most common would be the spark plugs, wires, fuel pump, fuel filter, vacuum leak, exhaust leak or oxygen sensors. Since there are many potential causes, I recommend having a qualified technician, such as one from YourMechanic, diagnose your car’s loss of power in order to have the correct repairs made.
