"My car is a 1992 240sx. When I drive and come to a stop sign, the car's RPM sometimes drop below 500 RPM and stall out. Does anyone have this problem? Sometimes it doesn't stall out but the RPM still drops down to 200 or
300 RPM then goes back to 700 RPM. Any
help in regards to this would be greatly appreciated."
"Most 240sx's eventually have an problem idling. This is related to the IAA valve which control the air mixture during idle. The two options to fix this are to have a dealer adjust the valve or simply have it replaced.
The symptoms are clear: as you hit the
clutch or lay off the gas and the car begins to
slow and idle the RPMs
may drop (sometimes quite rapidly) to extremely low levels, sometimes actually stalling completely. If this is happening have someone check out your IAA valve and you
may wish to clean all the ground wire connections for the car's ignition and injection
system."
