Sounds to me like the Throttle Position Sensor. Thats usually what makes the throttle "rev" But that is not going to make the oil pressure drop. Pull the codes from your car and look them up online. sometimes there is an extra fuse u can add to your panel and turn the key on and it will flash your codes via the check engine light. i.e. if the light flashes 2 times then small pause then 1 time and long pause that is code 21. if there isnt a extra fuse you can usually jump it with a paperclip and pull the codes. not really sure how to do that with yours. but im positive Google knows ;)

Is the check engine light on? Have you had the computer tested for fault codes? If not have it tested, all this is computer controlled.
