Run the diagnostics again...

Write down all the codes...

POST THE CODES HERE... we need to know what the codes are before we can help very much.

As for the vacuum leak... listen and try to figure out the area it is coming from... then look for a loose, broken or disconnect line.

Sounds like the vacuum leak is your drive-ability problem; listen or have someone else listen for that sucking sound; as above, cracked, broken or loose hose usually the problem (with vacuum).

If I am not mistaken, unless this is a Concours the 94 Deville is a 4.9 engine. Is this a Concours?
