Sounds like a vaccume leak.

Check the pcv valve for function and the brake booster valve.

Those are the most common

My '96 Mysteaq did that before it died.
Then I got my '06 xA

i went through many machenics before i came to one who suggested i replace my IDLE CONTROL VALVE. Made sense, can't believe no other mechenic could have come up with that. i had a manual prelude so i don't know if that helps.
