This usually means you have a failing ignition coil which is about a $200 repair at a shop. You will want to start by having diagnostic codes checked which can be done at your local parts store for free. If it indicates a specific cylinder misfire you will want to swap that coil with another cylinder and reset the codes, then if misfire follows coil you know coil needs to be replaced. You should be fine to drive it until repair can be done although it will continue to run poorly and not get good gas mileage. Let me know if you have questions, thanks.
