Question about 2003 Nissan Altima

2001 Nissan Altima with service engine light on

2 years ago had the service engine light on. It began to stall and not want to run. I could smell gas all the time. Took it in for service. They did a complete tune-up, changed fuel filter, spark plugs, etc. Problem got worse. The diagnostics showed a problem with the #4 fuel injector. Replaced fuel injector. Problem got worse. Next they replaced a gasket that had something to do with fuel. Now my service engine light is on again. Should I worry? Car seems to be running fine. How do I shut the light off? And does it come on when you reach a certain number of miles? I am at 64000. No problem with the gas cap. Have checked that.

I would check your intake gasket. Get your self ome carb cleaner in a spray form/can and perfrom this test. Run the car and spray the carb cleaner on your intake gasket which is right by your injectors. So pretty nuch spray it at the injector rail and listen fot change in idle, If the idle changes, the intake gasket is torn and you are running lean, because of a vaccum leak. Common problem on your model car. Perform test and let me know what you find.

2001 altima stalls at intersection or when AC is running and car is hot


No to the high octane gas. Regular gas is fine. Higher octane gas is more resistant to ignition and is better suited for high compression engines to prevent preignition and detonation. Check or replace your idle air control valve since the car stall at idle when the throttle blade is closed. If the IAC is not working it won't allow for air to bypass the throttle plate. Also have your throttle body cleaned.

Car stalls when hot or AC running at traffic light


Hello,
The most likely problem is the Air Intake Control Motor. On this car, I don't believe it is next to the throttle body. I believe it is on the opposite side of the intake manifold, and it is very difficult to reach. The throttle is on the driver-side of the manifold, but the idle air control valve, I believe, is on the passenger-side. It seems strange, but I believe it is true. It has four bolts holding it in place. You could also try to clean it using carb cleaner spray and the gunk should be dislodged and the problem will go away. If the problem doesn't fully clear then a new one is needed.

Good Luck!

2001 Nissan Altima idling high in parking or neutral


I have the same problem with my harrier 3000cc car. We have changed the idling sensor, airflow sensor. air filter, we have had the throttle checked, spark plugs, wiring and nothing works. The smell you are getting could be from your gear box, have it checked out early and if the gear shift is noticeable then you will need a gearbox specialist to open it and change the clutch plates. Good luck.

My 97 nissan altima is occasionally stalling out when I come to a stop. When this does happen it acts as if the engine is starving for fuel as I start it and for 10 or 15 minutes afterwards - it studders...


This happened to my 1997 Altima GXE a couple years ago. The coolant sensor is bad ($30-40 part). The coolant sensor is reading that the temp is cool on a warmed up engine and actually causes the engine to run rich (thinking it is a cold engine). The problem is intermittant and happened at the worse times.

My 2005 Nissan Altima loss power while I was driving down the street, the next day it cut off at a light, it takes a few seconds to start, but always starts


the 2.5 altima's had a recall on that problem about 2-3 years ago. Go to edmunds or progressive find the recall letter and the dealer will fix it free. well here you go:

section_opened.gif Recall ID # 07V527000 - ENGINE AND ENGINE COOLING Recall Date: NOV 14, 2007 Component: ENGINE AND ENGINE COOLING Model Affected: ALTIMA Potential Units Affected: 653910 Recall Details Recall Date: NOV 14, 2007

Model Affected: 2005 NISSAN ALTIMA

Summary: ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH A 2.5L ENGINE, THE CRANKSHAFT POSITION SENSOR CAN OVERHEAT CAUSING A BRIEF INTERRUPTION IN THE SIGNAL OUTPUT FROM THE SENSOR.

Consequence: IF THE INTERRUPTION IN THE SIGNAL FROM THE CRANKSHAFT POSITION SENSOR IS SO BRIEF THAT THE ELECTRONIC CONTROL MODULE (ECM) LOGIC DOES NOT HAVE TIME TO DIAGNOSE THE CONDITION, THE ENGINE MAY STOP RUNNING WITHOUT WARNING WHILE THE VEHICLE IS DRIVEN AT A LOW SPEED INCREASING THE RISK OF A CRASH.

Remedy: DEALERS WILL REPROGRAM THE ECM FREE OF CHARGE. CERTAIN MY 2006 ALTIMAS WHICH HAVE BEEN PREVIOUSLY REMEDIED UNDER RECALL CAMPAIGN 06V223 (NISSAN R0606) ARE NOT INCLUDED IN THIS RECALL SINCE THE REPROGRAMMING FOR 06V223 ALSO INCLUDED THIS REPROGRAMMING. THE RECALL BEGAN ON DECEMBER 31, 2007. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

Potential Units Affected: 653910

Notes: NISSAN NORTH AMERICA, INC.
