1995 nisan quest stalls

Try changing or switching out the distributor. Most likely getting hot and shuts down. Does it crank but no start whenever it stops? May only start when it cools down again.

Is the check engine light on? does it happen all the time? cold hot rainy damp sunny? Lets figure it out togther.

This is a difficult job and you should probably have a pro do it. Don't mean to discourage, just save you some grief in the long run. If you have a lot of experience and want to try it, this is probably the best site to check out:

Take it to a mechanic and have the cooling system checked, could be a bad coolant sensor.

Jeff did you figure this out. I am dealing with the exact same thing currently. Things to look at are Mass Air Flow Sensor (MAF), Throttle position Sensor (TPS), Air Idle control valve. I have played with everything but the Air control valve. I tried three different MAF, including a ghost sensor (circuit to match ressitance). I'm going to investigate the air idle control tommorrow. Let me know if this helps or if you get it figured oot

I worked on a '93 Quest last year. Couldn't find out why it wouldn't start. It was the distributor shaft not held onto its rotating gear. The roll pin had come out of the gear on the end of the distributor shaft. When the distributor cap was off, the rotor was turning with the shaft while the engine was cranking. So I thought that was okay. But when I put my finger on the rotor and it stopped turning, that is when I found out the problem. It's a stretch, but maybe the techs missed it. Take the cap off, and if you can spin the rotor either way just by hand, the distributor gear has come loose.

Looks like they really covered a lot. I suppose next they will you to replace the ecu. Good luck.

was the engine overheating before this repair? and again do u have bubbles in the coolant tank when the engine is running?, this is best checked when the engine is 1st started. I ask because I think u may have a leaking cylinder head gasket, this would account for the overheating still occurring.

with engine nice and warm,move distributor till it sounds right then drive it and if it pinks ****** it a fraction till it stops pinking,job done

I'm leaning toward a bad sensor, as in throttle body temperature, or coolant temperature sensor. The smell of too much fuel is probably from pushing pedal to start, which shouldn't be necessary on a fuel injected vehicle. What does it do if you leave your foot off the gas pedal during start? As far as fuel filter goes, if it hasn't been done in a while, I'd do it anyway just as preventative maintemance if nothing else.

hi
I think it was a catalytic converter problem
so change it may be fix a problem
with my best wishes
