check for vacuum leaks.

check your IACV to see if it clog up. another thing is you could adjust your idle rpm by turning the screw on the IACV. that's what I did with my s13. But also make sure you didn't have a head gasket leak. good luck

Use the Search function and search for a FSM (you can type "s13 FSM" as the search string.)

Also use the Search to find out "how to check IACV". There's a lot of threads with the correct info.
