I shifted from 3rd to 4th gear and my check engine light blinked for about 5 seconds then went away. I haven't been driving my car for about 5 days now and I'm nervous to drive it. Should I take it in? I read that this is a misfire, but I'm not sure if that means my car is drivable or not. Please help!!!

It could have been a misfire but the computer in your car no longer sees a problem or it would illuminate and keep on the Check Engine Light. I wouldn't be too concerned if the light is now off. If the Check Engine Light/Service Engine Soon light illuminates while you are driving, the car's on board computer sees a fault in the engines management system that is causing an excess amount of pollutants to be emitted from your car. This could result in engine damage if left neglected. Some problems that can cause the Check Engine light to stay on may take two "drive cycles' to complete before illuminating the Check Engine Light. The computer sees a problem and looks for an identical set of circumstances to occur to confirm that it has indeed seen a problem before turning on the light. A Check Engine light that continually flashes while you are driving is serious and is a sign that the computer sees a problem that seriously risks damaging the catalytic converter which may result in an expensive repair or even may cause a fire! Diagnostic codes are stored in the vehicle's computer and can be retrieved using a scantool that communicates with the computer in your car.
