Question about 2000 Pontiac Grand Am GT

2000 Pontiac Grand Am Gt won't start

We just bought a 2000 Pontiac Grand Am GT from a private owner. Every time we put gas in it, or the warmer it gets outside, or the more we drive it, it doesn't want to start. If we disconnect the vacuum hose, it will start. Sometimes we can reconnect the vacuum hose and it will stay running but it usually dies when we give it gas. No one seems to know what the problem is. I think we bought a lemon. One repair shop said a LOT of parts have been replaced on this vehicle so I think the previous owner tried to figure it out but just gave up and sold it.

    It the vacuum line to the EGR valve. We have not had it hooked up to a diagnostic yet.

Sounds like a defective EGR valve vacuum control solenoid or a defective sensor for the egr position.
