thanks for all the response guys!

I managed to get the idling to drop around 750 rpm when in Drive and around 1000 rpm when in N or P.

Just last week I ran into another problem however ......... my car started hesitating badly until I got to a Stop sign and the car just died. I manage to restart it but kept dying.

I'm wondering if the accelerator cable needs to be re-adjusted to bring the idling up a bit higher. I don't know if it's the OVP that might me causing the problem too. Is there any way that the OVP can be opened up and checked for flaws?
