Sometimes I will start the car and drive down the road. I make it to the traffic light and when it turns green get onto the highway only for the car to start to feel sluggish. I pull over and it struggles to stay on. I put pressure on the accelerator to try to keep it running. Sometimes it cuts off and when I start the car it no longer has an issue for the rest of the day. Sometimes the issue clears up without cutting off and I don’t have any more issues. One day before I left I revved the engine a little and got the issue to happen in my driveway to the point it produced a P0300 code for Random/Multiple Cylinder misfire. Any suggestions?
