Stop flooring it, simple

 

SO, it is like a hanging idle at 5k? Or 5K and still accellerating?

Ive had a similar thing happen where I accellerate, let off the gas pedal, and the rpms stay high and the car slows down. Kinda like a traditional transmission would do if you accellerated in 3rd gear then dropped it into 2nd.

Only happened to me twice as well, and not following wheel spin in my circumstance.

So I don't think it's as simple as "Don't floor it" lol although that was insightfull.

I too am curious as to what would cause this, however it seems transmission related.

Cheers...

 

Ya it just hangs at 5k its not accelerating..same problem as you

 

OKay. Well it's extremely odd. Happened once a year ago, and again about 6 months ago.

The CVT/entire car still works excellent otherwise. MIne has 131 kilometres on it now.


There must be others on here with similiar experiences? are we the only ones? lol

 

My 07 did that on numerous occasions after flooring it and getting wheel spin. My 12 altima has done it twice now, and I just passed 1600 miles. I'm not sure why it happens, but it doesn't seem to damage or hurt the car. I just let off the gas until the RPM comes back to what I would consider normal for having my foot off the pedal, and continue driving.

 

In my 07 I could just switch to "manual" shift mode and back to drive, and it would fix the problem. Now I have that silly Drive sport mode, so I just wait the couple of seconds for the rpm to come back down.

 

That happened to me before a few times, mostly while trying to accelerate onto the freeway from a stop at a ramp control light. It seems that if it detects wheel spin, it'll hold the rpm's regardless.

 

What Rupp and dakota said. Wheel spin.

 

My best guess is that the transmission is waiting to see if you want to maintain ~ the same rate of acceleration, which is keeping the engine rpms high to provide the same amount of torque that got you to that point - if you decide to punch it again. After it realizes you don't want more, it lets off after a few seconds.

 

Reasonable. ^

 

It has happened in my 6spd as well with a holding of an rpm. A few times I even had the clutch down and the rpms climed and leveled around those rpms. I just tap the gas lightly and goes down. Its really weird in a MT car than an automatic.

 

I seem to get that too, only when it gets stuck and I tap the gas it seems to lurch hard sometimes.

 

Same thing been happening to mine. Im pretty sure it has to do with the cvt. Its weird and a bit scary when it happens.

 

I have a Manual trans and it does it. So it is definitely not the CVT. I think it has to do with the Electronic throttle body. There is no cable from the foot pedal to the throttle body and is done with a pressure sensitive like switch you can say. I believe that's the culprit.

 

It hangs when there is wheel spin. Seems like poor ECU/TCU programming. Mine does it to. It's annoying.

 

You may have a flat spot in the TPS. You will only be able to diagnose this with a scan tool. Also try cleaning out the throttle body to allow the butterfly to move more freely. A lot of GM vehicles had this issue as well the Tracker.

 

That is a negative. Brand new altimas are doing it

 

This happened to me as well a few days ago. I was accelerating up to 50MPH on a street from a red light, tachometer read about 5000 as well, let off the gas, RPM stayed at 5000 and then dropped down a few seconds later. But during that split second of letting off the gas, I immediately tapped the brakes when I noticed my RPMs didn't drop. 2011 Nissan Altima 2.5S, everything stock, about 2900 miles.

 

Just had something happen today, I accelerate from a light and get it up to around 4000-4500 and the needle sticks there...for a good 2 minutes or so, nothing I did made it go down and then it finally, very slowly went down...weird...

 

If you want to fix it fast, switch it to manual mode and shift it back to drive.

 

Yeah that's what I do.

 

My altimas have never done this, but I came here to post a recommendation against trying to clean the throttle body, I had a throttle body fail after cleaning with injection spray on my old '02 2.5.

 

Well john.............That depends upon how you clean it. A throttle body is mechanical therefore cannot fail by means of simple cleaning. A TPS,IAC or a IAT can fail when someone sprays excessive amounts of cleaner. But the best way to clean a throttle body is open the butterfly wide and spray the cleaner onto a rag. Wipe the throttle body down,both sides. Now the second part of the cleaning involves 2 people. One to keep the engine RPM at 1500 and the other to spray cleaner into the throttle body. DO NOT choke the engine. This will NO where near harm an engine. We use to do this on just about every GM vehicle. But if the TPS is sticking the only way to know is with a scan tool and a DVOM. Everyday carb cleaner will do the trick.

 

As I've read here and on other sites regarding throttle body cleaning. You absolutely do not touch the butterfly while cleaning. As a matter of fact I would just leave it alone, but if you really want to clean use recommended cleaner. Spray the butterfly but allow to air dry or use some compressed air to carefully dry it out. If you more the butterfly be prepared to send your altima to the dealer to have the throttle body recalibrate.

 

I also have read you should absolutely never manually open an electronically controlled throttle body, to do so would usually damage it.

 

Incorrect. I have done this at least 1000 times in my career and never an issue. Whatever you read was false.

 

also if I'm not mistaken, the throttle body has a coating on the surface that requires a mild or a specific cleaner. Not just any cleaner will do. Please correct me if I'm wrong on either post 25 or 27.

 

Yes you are incorrect. Certain Ford vehicles back in the early 90's had a coating. But there was also a label on the throttle body stating "Do not clean".
