Hi all,
I would appreciate any insight into this problem with my 92 Maxima GXE.

Since a couple of weeks, the idle speed on my maxima has started
misbehaving. When I am at a red light, it fluctuates wildly as if the
car is going to stall. The car behaves fine when I am driving. This
only happens when I am in a stopped position such as a red light. The
problem is more noticeable in the drive position. It is less noticeable
in the park or neutral position.

My car passed the emissions test earlier this year with flying colors
so I am not sure if this is emission-related. Any thoughts much
appreciated.

Thanks,
Sunny

First and easiest thing to try, clean the throttle housing.

Seems like you could have a vacuum leak. Vacuum leaks can have numerous
origins. First determine if you indeed have a leak by trying the
propane-enrichment test.

Thanks you all for the responses..Since I am a newbie, I tried to find
the procedure to clean throttle body based on Steve's post but the
procedure on motorvate.ca illustrates it for a VG30DE engine (I think).
So I put it off until I found the procedure for a VG30E engine for my
GXE.

However, I tried diagnosing the problem using Chiltons. First, I tried
the ECU codes. In Mode III the ECU code read 0505 indicating no
problem. Then I tried the Mode 1 test to rule out the Exhaust Sensor;
again no problem there. I was going to try the Air Flow meter test
next, but the Idling got pretty wild yesterday, so I had no choice but
rush it to a mechanic. I was ready to shell out the big $$. The
mechanic turned out to be very honest. He diagnosed the problem within
a couple of minutes. It turned out to be a bad wire into the
distributor!! I think the wire between the ignition coil and the
distributor. He replaced it and problem was solved!!

>From the symptoms I observed, and from the various posts I read, I

never expected this problem to be caused by a bad wire!..Anyway, thanks
guys for all your support..
