Z does not accelerate

juld0zer

ok so i just went outside to check my car. my memory didn't fail me.

RHD models will have the cruise control brake switch on the left, stop lamp switch on the right.
LHD models will have it the other way around.

either way, it is the black skinny one you're after.

Thanks for taking the time to post and explain juld0zer. I will go to the dealer first but im anticipating a lot of BS+they will not solve the problem. Ill throw them a bone and try to explain the possible causes to this issue from what ive gather on what everyone has said and see if that helps. If not, guess ill have to follow your advice or live with this problem. Kind of bummed right now, and a bit disappointed with nissan

the brake switch could be the solution but keep your mind open to other possibilities as i know of a few other possible causes/solutions.

for me, i'm 95% sure it's brake switch related as i can induce the problem by simulating a depressed pedal.

keep us updated!

Hey P's Z, looks like you're not the only one, I've had this problem for quite some time. I thought it was the tune I had being too aggressive or dirty MAF sensors. Last thing I did was get an etune from uprev and changed to 93 octane gas. I haven't had the problem since. But it always happened to me in the mornings when I first started the car. Shut it off, turn it on again and it would go away. Let us know what the stealership says.

Will do Kabestro. This morning i cleaned air filters, maf sensors and disconnected the battery just for the sake of it since im pretty sure thisis not what is causing the problem.

Oh, and sorry to hear about you having the same issue, good thing you we're able to take care of it.

The problem continues and its happening more frequently. Went to autozone today since i havent been able to go to the dealer yet. Got OBD II readings and a P0101 code came up, even though SES light has not appeared. According to this site: P0101 Nissan Mass Air Flow Circuit Range/Performance OBDII Engine Light Trouble Code | Engine-Codes.com

Possible causes are:

- Faulty mass air flow sensor
- Intake air leaks
- Dirty mass air flow sensor
- Dirty mass air filter
- Mass air flow sensor harness is open or shorted
- Mass air flow sensor circuit poor electrical connection

Ive cleaned maf sensors, K&N filters were cleaned and are not over "oiled", checked for leaks could not find anything, so I guess this definitely leaves me no choice but go to the dealer. If its not a faulty maf, i can only assume its either any of the last 2 causes listed above. Assoon as i have more info ill report back.
