When the RPMs drop to 750 the oil pressure rises to the top an the revs go up to 1500- 2000 and every now an then the add coolant buzzer goes off. Can someone give me an idea where to look first or if someone has had this problem before tell me whats up? The oil level is fine. Help!

 

Oil pressure sender bad?
It's a common problem.

check it vs a mechanical gauge, i am betting the wiring is shorting out somewhere or the sender unit is faulty.

the idle issue can be a number of things, usually caused by an improperly set or faulty TPS sensor.

coolant buzzer going off means there is an air pocket in the cooling system, top off your coolant levels and drive the car, bleed it again as necessary until there is no air left in the system.
