Q: A possible misfire but don't know for sure - 2007 Chevrolet Cobalt

asked by on October 14, 2016

When I'm driving the car it drives fine idles fine but when I give it some throttle the car jerks hard just once and won't do it again until the next day. It seems to only do it when the motor is cool. It never happens when idle or after I've been driving for some time only a few minutes after start up in the morning. Could the be a misfire or something else? Another question is it dangerous to the life of my car?

My car has 124000 miles.
My car has a manual transmission.
