Few questions:
1. Did you ever change the fuel filter?
2. Did you ever experience any of these symptoms, before installing the new exhaust system?
3. Have you pulled the stored codes?
4. Are you getting any warning lights on the display?

1. The fuel filter was changed back in August.
2. There were a couple of times that the car did hesitate, but I just thought it was the nature of the beast. One thing I thought of is that the car is more prone to act up if there is another person in the car with me. I can't imagine another 180lbs would cause any problems. Just trying to give all the info I have.
3. I don't have a scan tool.
4. I have not had any lights come on except the service ride control. It comes on if I let the car idle for a while, but goes away when I start driving.

I am going to show my extreme ignorance now - I paid close attention when I started the car the last time. There was a vacume type sound and I felt a lot of air under the left coolant conector. After a couple of minutes the sound went away and the air flow did too. This is probably normal and I should know it, but I just thought I would mention it.

Again, let me thank all of you who are trying to help. I really appreciate it.
