I have 92 Maxima which will stall - sometimes restart and run fine and other time the battery needs to be disconnected momentarily and then it runs fine. This usually results in setting error code 12 I've checked for air leaks - cleaned grounds ( at least the ones I could find ) changed ECCS relay - I not sure if the MAPS sensor would cause this intermintant problem - Any suggestion? Thanks

 

clogged fuel filter. before I did my tune-up a few months ago the car stalled twice on me.

 

Have your catalyc converter tested.My car did the same thing I replaced all kinds of stuff like the fuel filter the battery etc.and it was the cat

 

I posted a similiar problem a few weeks ago. We finally got a code for the MAF sensor. Swapped it out, and voila...no more problem. Expensive fix, but at least there is no more hesitation/stalling

 

Was the problem with your car intermitant? I was thinking that if the MAF sensor was bad that you would see the problem all the time rather than intermitantly like mine is.

 

My problem was intermediate I can almost bet it was your cat.My car would stall out and then I would throw it in neutral and it would start right up.I put money down that it is the cat.

 

I'm not quite willing to put my money down...

In my particular situation, it was very intermittent (sometimes it would drive 200 miles without a problem, other times it would konk out 5 times in an hour). Spoke with several mechanics about the possibility of it being the cat, and they were very hesitant to even look at it as they all said a bad/clogged cat would throw off the O2 sensor, which would flick on the engine light just before the engine stalled. My light would never come on until the RPMs hit 0. Also, the fact that this guy seems to have to undo the battery terminal to get it going again really hints to an electronic problem, in that it sounds like whatever is acting up re-set's itself when the power is off. (this also happened in mine, but I did not need to undo the battery...only turn the key to the off position for about 45 seconds).

Best bet for the guy who started this thread is to take it to someone who has a diagnostic computer and let it stall until a code is kicked out. It took my mechanics quite a few stalls until they got a code.
