The truck is very sluggish when I throttle up to speed it almost feels like it's flooding. I do smell gas.

Hi,
If you have a fuel leak, that can be dangerous, so we need to get things fixed.
Where do you see fuel leaking, at the intake manifold or the exhaust manifold? If the exhaust, I wouldn't run it until it's fixed.
Also, have you experienced a misfire, and have you checked your fuel pressure?
Let me know. However, I want to start by scanning the computer. This vehicle has an OBD1 system that doesn't require a scan tool. All you will need is a short jumper wire or even a paper clip. Follow the directions in this link and let me know what is found:

Do this and let me know the results.
Take care,
Joe

Thanks Joe. I think it's leaking where the headers attach to the manifold, and I will get you the code. Any good guess what is causing it to do this?

Scott,
If it's leaking near the headers, that is a concern because it could easily start a fire. Also, when you say headers, which is what usually replaces the exhaust manifold.
Do me a favor. Upload a couple of pics where you feel it is leaking so I can see it.
