Q: Motor missing while accelerating

asked by on

The motor in my vehicle misses while I am accelerating.

In older vehicles, misfires during acceleration or under load are usually due to faulty spark plug wires. Other things like carburetor not adjusted properly, or weak valve springs can also cause misfires during acceleration. I would suggest seeking help form a qualified mechanic to assess why your engine is misfiring.
