Q: Car sputtering while idle.

asked by on February 20, 2017

After running errands yesterday, my car started sputtering. I drove the short distance home. It seemed to sputter most while idle. After reading many sites, I was reminded that it can take a little longer to get up to speed while driving uphill on the highway. A friend suggested that it may be a spark plug issue. Any idea?
My car has an automatic transmission.

There are many component failures that can cause this issue, ranging from a damaged or worn out spark plug, spark plug wire, coil, distributor, rotor or other ignition system components. Fuel system issues like a clogged or faulty fuel injector may also cause this to occur.
