#2146 of 2710 Check Engine Light On
Dec 27, 2007 (8:18 am)
I just recently purchase a 2003 Nissan Altima, 4 cylinder, S. Today when I was going to lunch, I noticed the car engine started shaking. I drove about three blocks and the check engine light came on. I didn't want to stop for fear of being stranded. I drove about one mile and the light went off and engine stopped shaking? I took it to the Nissan dealer (as I still have a warranty on it) but they wouldn't see it until tomorrow to check it out on their computers. Does anyone know what is wrong with my car? Please help!

Sounds like you lost a cylinder there for a minute---either faulty coil/igniter/spark plug/wire (not sure what your engine uses) or maybe a bad injector. I bet the code will show a "misfire" in a certain cylinder.

isn't there a recall out for the cam and/or crank position sensor? and wouldn't that cause the same thing.

not a crank sensor. That would cause the car to go dead I think and not restart, whereas the bad cam sensor will cause the engine to die but restart for a short drive, then die again, etc. Both of these should throw the CEL as well as error codes.
I'm still gonna go with weak coils or some other problem relating to just one cylinder.

You did not say how many miles are on the vehicle, but I would guess high since it's a 2003, probably 80,000 or more.
Lot's of things could cause that miss. Here is another possibility:
This symtom could also be caused by engine coolant entering a cylinder, the same thing happened on my daughters 2002 Altima 2.5S, with 100,900 miles. Watch the coolant level in the resivior and radiator, check the radiator ONLY when the engine is COLD. If you mysteiously loose coolant without any apparant leak, it could be the problem. Also watch for steam out the exhaust pipe, AFTER the engine has warmed up. It is normal for most cars to emit a small amount of steam and water out the exhaust pipe when first started, and for the first few minutes while warming up. This is because gasoline turns into mostly water when it burns. It is in the state of steam in the exhaust stroke, then when it enters the COLD exhaust pipe and muffler, it condenses back into water that you can see. Once the exhaust pipe and muffler are hot, the water remains steam and you don't see it, unless it comes out into cold air. If you have coolant leaking into the cylinder, it will often come out the exhaust as visible steam because of the volume of the coolant and it also causes the cylinder to misfire. This may or may not show up in a code, depending upon how bad it is.
These engines are KNOWN to warp heads, my daughters Altima 2.5S head was warped .005" and had to be milled at the machine shop. After rebuilding the head and putting it back on a week ago, it is doing fine so far.
If you want to know more about the work I did on the engine, you can go look in the Nissan Altima Engine Failures forum. There are long discussions there about the problems with the Pre-cats, Catalyic Converters and engines. Use the SEARCH feature.

I'll take a stab at this one: I'm willing to bet its the cam or some times called the crank sensor. Nissan has a factory recall on this issue that started in August of 2006. You can call Nissan at 1-800-647-7261. They will re program the engine control modal (ECM) for free. Low speeds and stop and go driving can cause the cam sensor (located at the top of the engine -inline with the distributor) to overheat. When the sensor over heats it gives false signals to the ECM. The ECM will try to correct the engine timing which will cause the engine to vibrate, which in turn is picked up by the knock sensor (detects engine vibration) - which will shut the engine down before the vibration causes mechanical failure.
Please write back and tell us what the dealer tells you.

#2154 of 2710 Altima Remote key/Sensor issue
Jan 01, 2008 (2:42 pm)
Can you please help with this vexing issue? I bought a 2002 Nissan Altima 2.5 SL new from the dealer 6 years back.
The remote for our Altima had stopped working. Initially the car used to respond sporadically, but without any sounds (usually associated with locking of the car). But after sometime, it stopped responding completely. I thought it's the battery in the remote and got it replaced. But the problem continues. Never had this problem in the last 6 years.
I, now, suspect that it's an issue with the car sensor. have you guys heard/seen something similar?
Thanks in advance,
