Need help with my 370z
 

So I was just driving around last week and stopped to a Red light. After Green light shows up, I hit the gas and as I was accelerating suddenly the car is doing a STOP and GO motion while I was pressing the gas. So I was freaking out and pulled over right away, waited for a couple mins and decided to go again and after that car is fine and didn't do the stop and go motion. This is the first time it happened since I got the car.

Today, I was just cruising around and came to a Red light. After green light, I hit the gas again and as I was accelerating the STOP and GO motion started happening again while I was pressing the gas and SERVICE ENGINE light came on. Idk, what's the problem but I was guessing that it has something to do with the FUEL PUMP or FUEL INJECTORS. Can somebody confirm this for me? I've only owned the car for over a month and bought it preowned. It's AT transmission and I do have warranty for this car

how much gas do you have in your tank? sounds like the fuel starvation issue that commonly happens.

My tank is always Full. Only used premium. I put gas every week before it even hits half of my tank

O2 sensor may have went bad ? Just a guess but you can confirm by reading the code with an OBD tool and confirm what code it is throwing, then you can proceed from there.

Thanks for the reply but what is OBD tool? Sorry but I'm a complete newbie to this stuff. About to go to Nissan tomorrow to have it checked

Don't go to Nissan. Go to your local Auto store, ask them to scan the car with an OBD reader to get the codes. It will be much easier to diagnose with the codes.

if youre outta warranty I wouldn't go to the dealership. Go to an indie shop you can trust or is recommended in your area.

also have you checked the fuel pump?

I'm going to guess fuel related. Injectors, pump, filter.

Please describe stop and go motion in more detail with simulated sound

Preferably in the form of a video. Hold your hands out as if gripping a steering wheel. Also incorporate the emotional feelings of the situation on your face when the "stop & go motion" starts.

Yea, follow what BC and Sgt said. Out of warranty, stay away from the dealer. Any reputable mechanic shop in your area can hook up the OBD scanner to read the codes and let you know what they are.

Hahaha :roflpuke2:

Fixed. ;)

Thanks buddy, I appreciate it. ^^

Just got the car a month ago and the warranty has 3yrs on it

I got 3 years warranty on the car and I just got it a month ago. So I should be fine to bring this to Nissan dealership right

actually the stop and go motion happens whenever I reach 2,500 rpm. Kinda like the Car is about to run out of gas but my tank has plenty

Dude, if it's under warranty bring it to the dealer.

YzGyz

If that is the case then absolutely bring it to the dealer. Was under the impression you were out of warranty for some reason. But is it a factory warranty from Nissan or an extended type of warranty purchased through the used car dealer (non nissan) that you may have purchased the car from ?

dat is called limp mode.

Drentooth, is your car manual or automatic? Also What was your oil temperature at the time this happened?

My guess is one of the sensors have gone bad. I doubt its something major. Check with your dealer since you have warranty.

I thought limp mode caps you at 3.5k RPM

Have warranty=use warranty.... use it as much as u can as often as u can

Drive it with VDC off. If it still does it then do what they say above. If it goes away, you're getting some wheel slip and VDC is kicking in. Lighten up on your foot and drive with a little more finesse. You can use the VDC indicator to see how far you need to lighten off. Once you get the balance worked out, turn the VDC off again and see how much further you can push it before the car comes loose. BTW, do your driving development at your own risk. Many people wreck while developing performance driving skills.

One other thing you can check... Lift up the rear and look at your half shafts. Make sure the sprocket for your half shaft sensors isn't caked with crud. They can be dirty, but should not have any chunks of crud on them. These sensors tell the computer how fast each shaft is spinning if the difference is too great, it will apply brakes to the one that's spinning too fast.

Hmmmmmmm

1)Has warranty........ Use the warranty......
2)There are other speeds that 'foot to the floor'........
3)Road Atlanta.... get a helmet


Reputable shop in the Atlanta area: Z1. You will just have to drive like a grandma to get there....:eek:

I've had limp mode that won't let me go past 1100 rpm
