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. This is a random occurrence; not all the time. Can you give me a list of what might be causing this so I can get this fixed?

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.

Q: Rough idle and SEL is flashing. I've replaced all 6 plugs and coil packs. The car still has a rough idle and no power.

Misfiring can be caused by lack of spark or lack of fuel. If the same cylinders are still showing codes for misfiring after replacing the coils, the problem can lie elsewhere. If it is the coils not firing, there can...

Q: Car starts and then stalls.

If the problem started directly after changing these things then you need to make sure the parts you installed are the correct parts and are correctly installed (i.e. no leaks). Fuel filters are directional flow and fuel should only flow in...
