VACUUM LEAK ON

2000 Toyota Celica • 4 cylinder FWD Automatic • 100,100 miles

Would a vacuum leak on a 2000 celica cause engine performance to drop from 30MPG to less than 20?

That is possible. A vacuum leak would affect the idling speed and O2 sensors which would indicate a lean condition and inform the compuuter to enrich the running.
