Low Idle in drive??

[EG240]

Hello. I am new to Zilvia.net.
I own a 89 240sx. When I am in drive and the car is at standstill the car idles very low. what causes that problem.
the car runs fine otherwise.

Check for any vacume leaks. That would be my first guess. I accidentally left my oil cap off and the car would barely Idle.
