First: check the vacuum lines in the engine compartment. If it started right after changing oil, you might have loosend a line unintended. If you have an Euro-model don't forget to check adjustable headlights.
How about central locking system? Does it still work, when the engine has been out for a while? Check both opening and closing after a while.
