I have a 95 concours and it seems to be acting up. It bogs down when I give it some gas and makes a funny noise. Not necessarily tapping or knocking but it is definently a noise. At first I thought it was the catalytic converter but now im not sure. Any one got any ideas of what this can be. The car had a little over 200,000 miles. The engine seems strong as it's a northstar. I just cant seem to figure out what the heck is wrong with it.
