thanks to all who posted to my question before. I did try the new gas cap, no luck. Before I pull apart the vacuum lines at the smoke test port, could anyone tell me what size that line is, so I can pick up some new line before I tear it apart? Thanks, and I'll post once I get at it.

You need to just checking vacuum hose's. Do you if you have an LDP pump or NVLD?

Not sure. Can you tell me how I'd figure that out?
