'93 Maxima stalling issue

That is pure BULLSHIT! emitting a high pitched freq. that is affecting plug wires....MY GOSH! Oh yea and my piston skirts need hemming.....do you have a needle and thread? Try taking a look at the mass airflow sensor...there is a cause but it aint a chip producing a high pitch freq...... RUN don't walk, RUN away from that mechanic!

Nope, not at all. That's about the dumbest thing I've ever heard come out of a mechanics mouth!

I have a 93 Maxima GXE with 121K miles. I have a similar problem in mine, but it doesnt stall yet. Instead, it is idling rough, with the idle rpm in drive being approx. 600 rpm. In Neutral or PArk the rpm rises to 700, and hence doesnt vibrate then. When I change from Park to Drive, the rpm first dips very low, till about 400 rpm when the vibration really shoots up threatening to stall, and then creeps back up to 600 rpm wit hstill significant rpm. The mechanics I have been to, havent been able ot diagnose the problem either, with recommendatiosn ranging from major tune-up to injection system cleaning, to injector replacement to transmission service etc. I have no idea how to solve this either....the car runs like a dream otherwise.

In follow up to my original message ......

I had never experienced the problems I first described until today. My fiance mostly drives the car, and each time I took it for a test drive, I would never encounter the problem .... until today. It first stalled while I was at a red light. I had it in first with the clutch in and it just died. No bucking, no nothing. Just dead. It next stalled when I was rolling to a stop. And, on occassion, it would not react when given gas. I would have to take my foot off the gas, then give it juice again. And at another point, I was travelling at a steady 30 mph on a long stretch and it would slow down, acting like it wasn't getting any gas although I had the pedal depressed slightly. Very weird. iI don't think it's the fuel filter, as it has get-up-&-go when you step on it. Going through these threads, it appears a lot of Max owners have had similar problems, but no one is really sure of a fix. So, maybe my mechanics theory of a high-pitched computer chip isn't so bizarre.

Your problem seems a little different from mine. The stalling on my vehicle just started to happen without any warning. The idle never dips low, unless, of course, it stalls. And when it stalls, it just happens without warning. There's no bucking or vibration.

It sounds as if you have a SE model with a VE30DE engine, which are useful information in diagnosing your problem. If you search groups.google.com for the terms "VE30DE" and "Stall" you should receive two threads. Click on "RE: 92 SE" and read NissTech's response:

This is a common problem.

when the coil's go bad the emit RF (radio frequency) interference, this rf interference get picked up by the main engine harness and travels along the wires to the ECM,

The ECM does this noise / interference and get's confused , hence the car feel's like it just shuts off. In follow up to my original message ......

Thanks for the thread, Ryan. I'll look into it. Seems to follow along with the mechanic says.
