While I was driving on the highway, my engine light started blinking. There was no change in the way the car was acting, which was normal, until I got off the highway to a stop light. As I started to drive away, the exhaust sounded funky as if it was choking or had a leak of some sort. When I got to the house and parked it, I revved it and it sounded rough. I went back and felt the exhaust and it wasn't flowing smoothly, more like a puff puff puff puff type pattern. While sitting in the car I smelt something that wasn't normal but I can't describe it as anything more than kind of an abnormal smell. I threw the diagnostic tool on the OBD plug and came up with the P0300 code. From what my experience is telling me, is to check spark plugs and cables. Also as a bit of extra info, the spark plugs, cables, coil packs, and ignition module were all replaced last summer and only about 8,000 miles put on the car since then. Any further insight on a possibility for a solution, if it is not the spark plugs or the cables, would be greatly appreciated.
