Alright, I just had my coils replaced and now I fear something else is going wrong.. This morning when I started my car and put it in reverse, I had hardly any power, there was a clunking noise, and it took like 30 seconds for my car to actually get going like normal. I drove to pick up my girlfriend and to starbucks and both times it started fine. After workout at school, I come back out to my car and start it.. Same problem witht he clunking noise and power situation. The clunking noise seems to be coming from up front in the middle.. What could this be? Thanks in advance..
