I made a point not to touch anything that wasn't necessary when I did my tune up. The fuel mixture and timing should all be exactly the same as before. The car always ran fine until one morning it only ran on five cylinders. So in theory, after the tune up everything should run perfectly. Although it now runs on six cylinders, I still have that low power problem. I'm still waiting on the connector, but this should narrow it down to a vacuum leak. I hope. Now all I need is time! I'll let you know. Thanks again to everyone. payne
