2003 Nissan Altima stalls at intersections/ stops

This sounds like a Camshaft or Crankshaft Position Sensor is failing, but can be any multitude of problems. Get the Check Engine Light scanned and report back what code you are getting.

I’m happy to help further over the phone at https://www.6ya.com/expert/jeremy_69f3cc28d95bf514

you need to replace cam sensor(po340 and reason for stalling) and perform an evap system leak test (po442-small evap leak).

VERY interesting ... Rodney2764,

I HAVE seen similar issues before...

Everything else seems to be good. I would be
thinking about having an EXHAUST shop look
for a loose MUFFLER baffle or collapsing
CATALYTIC CONVERTER...

A rusted or loose part inside can COMPLETELY
block EXHAUST OUTFLOW...

It is not a COMMON trouble... but certainly worth
the look (while you are mobile (my opinion...
RATHER than WASTING time & money
buying A WHOLE lot of UNNECESSARY oxygen
sensors ( get mistakenly replaced )...

(( from "FREE" code readings )).

((( really difficult to resolve when you are immobile ))).

Hope this helps...

you might want to look at your O2 sensors, they can cause the motor to run lean or rich. also you might have an electrical issue that is tripping your ECM. your electronic control module might be faulty. best solution is to get a trouble code reader and find out what your on board computer has stored. from there you can repair and clear the codes.

It's possible you have a bad (broken) engine mount.

your crank sensor is goin out soon this a common problem with altima.i hope this will help,have a wonderfull holiday.

Your timing is off, need new alternator, or get the free Nissan recall done where they reprogram the computer to run at higher RPM.

tell your mechanic to look up Service Bulletin #96-032 this could fix your problems

If you have a Service Engine Soon light on, then having the computer scanned for codes would be recommended. The code could indicate what the problem may be. The most common is cam and crank sensors.

I would have it checked to verify.

Thanks Jay!

SOUNDS LIKE THE IDLE AIR VALVE IS CARBONED UP TRY SPRAYING CARBURETOR CLEANER INTO AIR INTAKE AT THE THRUTTLE BODY WHILE HOLDING IDLE SPEED AROUND 1500 TO 1900 RPMS USUALLY AFTER SPRAYING FOR SEVERAL MINUTES ABOUT HALF A CAN THE PROBLEM WILL BE FIXED ...IF THIS DOES NO GOOD YOU MAY HAVE TO TAKE IT TO THE DEALER TO HAVE THE IDLE SPEED REPROGRAMED IN THE ECM WITH THE DEALERS DIAGNOSTIC SCAN TOOL....USUALLY FOR AROUND 50 TO 60 BUCKS HOPE THIS HELPS
