30 seconds of searching could have netted you the info 18 hours ago. Stock 240SXs came with a 4.08.

Usually means its time to replace your PCV valve.

Bleh, so I are no read good today, sue me.

Anyways, pulling the oil cap off, changes the pressure inside the crankcase. It screws with MAFS readings. Normally, the engine will just run slightly rough until the cap is replaced. If your idle keeps dropping, and then stalls out, its possible you have something wrong. You may have a stuck PCV, or bad blowby. You could also have some misplaced vacuum lines. Its hard to say for sure without being able to run any tests. Is the engine stock, and how many miles are on it? Does it burn oil/coolant?

has a cold air intake. other then that bone stock. 123.XXX. burns nothing

Either way, replacing the PCV valve can be one of the tests, they're like $3.
