My car hesitates or stumbles

Nissan Altima 2003  288000 miles
I have a problem with my car, 3 months ago the engine started with a hesitation or stumble when reaching 2000 rpm. First, my husband did the tune up (the only thing he didn't do was changing the fuel filter, as in Autozone he was told that it was only sold together the fuel pump). We then took it to the mechanic and he changed the crankshaft sensor. Also, the check engine light was on. The mechanic says it is the timing belt, but we don't know if we should try to fix or get a new engine. A couple of weeks ago we were driving in an uphill road and the hesitation started again, do you think is's… Read complete

My car had problems similar to yours, but I didn't get so many errors, only P1101 I think it was. It had to do with the maf sensor (mass flow sensor) which I changed and solved the problem. The issue I had was that I could not push my engine beyond 2300 rpm before It chokes. It is possible that the new crankshaft sensor they used on your car was not original (as they are much more expensive), and those don't usually last long as they have poor quality. Even then, I don't think the sensor was causing your original problem. I would advice you to take it to a Nissan diagnostic specialist so they can tell you exactly what is wrong with your Altima. I've had this car for 2 years and this is the only problem I've ever had.

Thanks and good for you, we still have our car stopped. Right now it is at our third mechanic, as the first one said it was an electric problem but it wasn't, another one made us buy some parts that did not fix the problem (and then wanted us to change the computer, which is really expensive and it is not under warranty) and now we are with another Nissan specialist someone recommended us that thinks the problem is in the cylinder head. I hope we can finally fix this!!

Hi, the most common cause for stallings and jerks are the crankshaft and camshfats sensors, they are sold together originals.

I'm sure the problem is the MAF sensor, which measures the mass of air flow and sits after the air filter.

I have a Nissan Sylphy 2013, loss of power when accelerating and have to pump the gas peddle before it picks. What do u recommend I do

I had the same problem twice with my 2003 Altima 2.5. When I tried to accelerate rpms did not go beyond 1500rpm, as if it choked. The first time it was due to the MAF sensor and the second time was 7 months after that. At the beginning I thought It was the same sensor again, so I even bought a new one, but it turned out to be a different new problem. I first took it to a couple of a mechanics that did not agree on the problem, and then finally to the Nissan specialist who by only hearing the noise could identify the problem: the catalytic converter was clogged. He removed it, and problem gone. He said I could put a new one, but It was too expensive, so que replaced it with a straight pipe.

There was a Nissan recall announced July 7,2006, (see "carcomplaints.com"). I have the stalling problem and noticed the recall. I called Nissan Canada and the recall is still accepted. I have just booked the recall repair. I have already had the cam shaft sensor replaced very recently. Hopefully, this Works. Here is the car complaints information --- "Summary: On certain passenger vehicles equipped with a 2.5L engine, the crank angle sensor is affected by temperature variations. Under certain driving conditions, these variations in temperature can be large enough to cause a brief interruption in the signal output from the sensor. Consequences: If the interruption in the signal from the sensor is so brief that the eletronic conrol 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. Action: Dealer will reprogram the ECM free of charge. Overall, a poor vehicle that can bleed you dry while safety is significantly compromised. This recall repair will be the last money spent on this vehicle. If it stalls again, it's gone.

Engine starting

Nissan Altima 2002  128000 miles
It takes long for my Altima to start working and, when it finally does, revolutions go down and suddenly stalls. This happens time after time and even sometimes a kind of explotions can be heard coming from the car's exhaust. In order to start the engine I need to keep the accelerator pressed as it takes quite a long time to turn on. I was told to change the fuel pump, but at the same time read on the Internet that, in most of the cases, this problem has to do with the crankshaft's and camshaft's sensor. Which is your recommendation?

I consider that your problem must be in the crankshaft's and camshaft's sensor as you mentioned. The first one could be cutting of the spark or the last one not opening the injectors and that is why you hear explotions.

In order to make sure whether the pump is the cause of your problem, you should install the injector cleaner and check if it accelerates and works. If it does then it is the fuel pump.
