View 1 RepliesMy 2003 Altima (generally trouble-free!) recently lost power ... it would just putter along at 5mph. I parked, and the engine revved up fine. Waited a bit, put in drive and and same issue. I punched the accelerator, it sort of backfired and then ran OK. Next day, I called the local auto center who thought it could be catalytic converter blockage. They ran test for error codes and one stated check engine light was out of order and that instrument cluster should be replaced. They admitted it was bizarre, so I declined the repair and have driven just a handful of miles in the few days since. Today, power lost again, same 5 mph-only issue. I park, turn off engine and wait a bit. Then it wouldn't turn over... some blinking lights in the instrument cluster. So... it's been towed and tomorrow the same auto center will investigate.
View 12 RepliesMy wife's 2003 Altima has been stalling. The MIL came on P0335 Crankshaft Position Sensor Circuit. I did a little research and it seems that it is pretty common for that sensor to go bad, so I bought a new one. The problem is I can't get the wires off the old one. It is in such a ridiculous place. There is no line of sight anywhere. It has to be done completely by feel. Supposedly, I should be able to push the button until it clicks and then remove the connector. When I push the button, it definitely clicks - but it doesn't stay clicked. It clicks right back out before I can pull on the connector. How can I keep that button clicked in when I can't see anything and I can just barely get one hand down in there?

View 4 RepliesI have a 2001 nissan altima. About 4 weeks ago it started over heating, smoke coming from under the hood, not the gauge raising. I took it to my mechanic and he replaced the big hose going from the radiator to the engine. I got it back and about 2 days later it started again overheating again, smoke under the hood. Took it back and he said the radiator is leaking it was under a year old so he replaced it, i drove it home on a sunday and monday morning I drove to work 5 miles at 10 am break it had two puddles under it. He said it's the radiator again, replaced it and we went to pick it up and he said it blew again. Sounds odd to me He finally said they thought it was the fans. The gauge never ran hot only the smoke coming from under the hood. If your looking under the hood it was wet on the left side. Needless to say he has had my car for almost 2 weeks and it's still not fixed. My question is should I go get it and take it somewhere else. What damage will it do to drive it somewhere else?

View 9 RepliesI am the original owner of a 1993 Nissan Altima. My mechanic states that the air intake (part # 165751E400 "air duct")has dry rotted. He put some silicone hoping that would seal it but it did not work. The part is no longer available from Nissan. The car runs very rough and wants to stall when coming to a stop. It also smells like gasoline in the cabin and the gas mileage is terrible 17 mpg. I have tried to find someone who could custom make a new hose with no luck. My mechanic stated that pulling one from a used car would have the same problem. What other options are available? The hose is about 8 inches long and about 3-4 inches diameter. It has other small hoses that attached to it. Do I throw away an otherwise reliable car?
View 4 RepliesI've noticed a creaking sound coming from the left front wheel when I go over a couple of particularly large speed bumps. I have had a lot of problems with the suspension in this car, and have replaced the front struts, the front right control arm, and the sway bar links and bushings. My best guess is that this noise is coming from the front left control arm, as it has not been replaced, although my current mechanic says that the front left control arm is fine. Also, it has been under 10 F here the past few days, so this could also just be a result of the cold weather.

I have a 13 Altima and have been hearing a clunk/pop sound when coming to a stop and sometimes when changing from park to drive and park to reverse. It seems to also be there when accelerating too and the car is also seem to be vibrating when moving at lower speeds. Today i noticed something else. I parked the car and took the key out. I went to the side of the car and slowly rocked it back and forth and started to hear this clunk sound. I have uploaded it to youtube and can be found here [URL].... . After hearing the sound, I decided to take the driver wheel off and noticed it makes the same sound when i move the tires. It seems to be coming from the CV joint, where it connects to the transmission. why would a car make that clunk sound with the car/key off and swayed back and fourth? does this seem like a CV joint issue or something related to the transmission.

I already replaced the MAF so what else could it be I cleared it once and the cel came right back on. I have a stasight pipe from the catback on my car and the cabin started smelling like burning plastic and eggs every time I accelerate. I'm going on a road trip tom and was wondering if I'll be fine. The car has a bit more noise coming from the engine the usual more like a swiping tapping noise
i have a 2003 nissan altima with 99288 miles on it. i just got it changed yesterday and one of the tech's showed me and said there was condensation on the oil cap and the oil was dark. he recommened an oil system cleaner. is this accurate or is there something more i should worry about? he also said i was 1/2 qt low. last time i got my oil changed at the same place he said my oil was 2qts low and recommened a semi sythenic blend to flush things out, which i did do. i usually get my oil changed about every 4000 miles or so, i try for 3000 but not too successful. i also drive 1/2 hr to and from work every day at a min.
View 11 RepliesAs I was driving home, I came to a stop. When I depressed the accelerator to move, nothing happened. No gas was getting to the accelerator, the car wouldn't move, but the engine was still running. So I shifted the car in park and back to drive and I began moving. This happened on several occasions.
What is the problem? The gas filter? The gas pump? The fuel injectors or The transmission?
So, my family owns a 2006 Nissan Altima, and it's developed a strange problem recently. It would start fine when cold, but then if I park it and come back 20 minutes later, it won't start again. Apparently this is a thing that happens with Altimas. Now for a while, it was starting after two or three tries, but now it just simply isn't turning over. When I watch it under the hood, it shudders some, and then there's a puff of warm air/exhaust, i don't know. I've read it might be the cam shaft sensor, but after replacing that the problem hasn't gone away, and a few people have said it might be the fuel pump, but I replaced that as well and it's still not starting up. I'm thinking i might try to replace the crankshaft sensor next but I thought I would ask here for advice and opinions just in case. This isnt the first time this has happened with this car, apparently - this happened once before, and the camshaft sensor being replaced fixed it.
View 15 RepliesI have a1997 Nissan Altima 140k miles with the manual transmission. I have a fuel problem that I can't seem to solve. every 1-2 days and only intermittently and unpredictably my car starts to idle up and down and occasionally if I don't give it enough gas they car may stall but the stalls only happen when I am not pressing the accelerator, meaning only at resting idle. since I am fanatic on washing my engine, I initially though that spark plugs were dirty or not working, I changed the spark plugs the distributor cap and the wires but the symptom continues. then I check the resistance of all the four fuel injectors and all of them read at around 12.8 ohms. I have also treated the fuel system twice with injector cleaner, the kind that you find at a gas station but still, the problem persists.
if it is not too much trouble I have another smaller questions. if the car sits overnight or for a couple days, the shift is really easy but as the car warms up the shifting becomes harder. could the transmission fluid need to drained and replaced?
on 1997 Nissan pickup 2.4-liter engine do you have to take off the valve cover to clean out EGR ports.
View 1 Replies2003 Nissan Altima 2.5 SL automatic - starts fine when the engine is cold but won't when the engine is hot. It acts flooded. I've changed the camshaft and crankshaft sensors, spark plugs, one spark plug coil, radiator, valve cover and the coolant temperature sensor. The car will turn over but will not start - sometimes it will after 5-10 minutes of trying.
View 1 RepliesMy wife has a 2001 Nissan Altima GXE with 89,000 miles. The car seems to run hot with the temp gauge reaching the "H" but never passes it, andwhen air conditioner is on it blows hot air; Then the car cools down it the air cools again, and this seems to happen all of the time.
Now, it's been happening for at Least 3 months, during this time it has had a tune up, the radiator flushed & hoses, thermostat replaced & lastly the ..... Sensor has been replaced & still the same thing happens the car temp runs hot cold up then down. We are at a loss here.
I have a 2001 Nissan Altima. I seem to be having a fan problem. I started noticing that about 2 seconds after I turned the car off, the fans would come back on and run for ~25-30 seconds. I brought it in and my mechanic was thinking maybe a defective thermostat, so we replaced that. It still keeps happening, but now I've realized that the fans come back on anytime the car is turned off when the fans are running. If the fans are not running, they won't come back on. I've been trying to pay more attention to what is going on and when I first turn on the car, no fans are on (at least not the high fan, not sure if there are more than 1) After driving around town, the fans will turn on.
Normally, I believe the fan should then turn off once the coolant temp gets below a certain level. I let the car sit idling in the driveway for 15 min and the fans never turned off. I took it back to mechanic and repeated the idling for 15 min, fans never turned off. He checked the coolant temp with some sort of sensor and the temps were reading between 166-170 depending on where he aimed his device, so he said the fans should be turning off and it doesn't seem like the car is overheating.If he unplugged the temperature sensor, the gauge would go all the way to cold, but nothing changed for the fans, so he didn't think that was the problem.He took the fan relays along the edge of the car and swapped them around and nothing changed, so didn't think it was a relay problem. He removed some sensor on the passenger side on the back part of the engine and the fans got really loud and really fast. When he replace that, the fans would go back to normal until the engine temp got hot enough to turn them on and then they wouldn't go off again. He's thinking that sensor might be the problem, but isn't 100% sure. I think he said this was the cooling fan sensor or switch.
On a side note that may or may not be related. About 5 years ago the water pump broke. It started having the fans on all the time (even from a cold start), that turned out to be a faulty knock sensor. There was a knock sensor code and he replaced the knock sensor and then the fans went back to normal cycling. I didn't have any problems until early last fall, when I started noticing my current problems. I didn't worry about it until now, because as it got colder outside, it wasn't an issue. So outside temperature definitely effects it.
There are no codes this time.
2006 Nissan Altima 2.5s.
I started my car yesterday and the radio came on as normal. When I turned off the car, it did not shut off as normal. This continued through a couple of stops.
When I got home and turned off the car, the radio was still playing. I disconnected the battery, the radio stopped. I reconnected the battery and now the radio will not turn on but everything else in the car is working fine.
