About 3 weeks ago I went to start up my 2009 Honda Civic Sedan lx and lights came on and everything but wouldn't start. On the third time trying to start it none of the lights came on, so I changed the battery. I tried starting it with the new battery, all lights came on perfectly, but it wouldn't turn over. I changed the starter and the car ran fine with no problems for maybe 2 weeks. This morning I was driving down the road when the check engine light came on and the engine suddenly started to rev up uncontrollably. I was able to brake but it was very hard to do because the engine kept revving. Without my foot on the brake the car was going 30 something mph, when I braked and got below 15 I felt a hard downshift. Has anyone had these simliar problems or know what might have cause this kind of behavior? 3 Answers
