Mine has to be warm to experience it.

 

Yeah.. I am sure u read it before but same here.. In the mornings my car drives normal.. When was the last time u changed ur tranny oil?

 

I am also having the same exact problem

 

I'm going to attempt to reset my ecu. If that don't work then I will take it in to the stealership and see what they say. If all else fails then I will just drive my G into a wall cause this BS is frustrating!!!

 

Haha trust me , I am right there with you.. Plz post the outcome of reseting the ecu.

 

Well good news fellas! Did the reset and the car is back to running normal! FINALLY! I had a feeling that this would do the trick. Just finally had the time to do it. Just took off the negative terminal of the battery, press and held the brake pedel for about 10 seconds or so, hooked the negative terminal back up, and went for a drive. No hesitation what so ever. Do the ecu reset and let us know if you car returns back to normal.....

 

Have you looked into the ECU reprogramming TSB?

^ where you been? havent seen you post in a long time or at least not in the sections that i visit lol. Did u ever sell ur car or u still have it?

 

i did read every comment cut i can tell u this.. i have an o7 and i know what u are talking, its not the problem of the spark plugs.. the car is just slow on the take off.. the rpm's will go a lot higher then what u are expecting b4 the transmission kicks in to bring u to that ideal performances that u are thinking off. One thing u can do is turn off the traction control. Now if u have MT then u are shifting wrong but if it's an AT then.. u can't control it..

 

I don't quite understand your post. But I have a MT and it is not about shifting wrong. It feels as though the throttle bodies snap shut for a split second as the rpms pass 1k rpm and causes the car to buck. If you ever drove a MT in a parking lot or in stop and go traffic you would understand how irritating it could be to have the car buck and have to constantly slip the clutch to get the car past 1k rpm. So unless you plan on slipping the clutch the whole time you drive through a parking lot you could understand the frustration. I'm just glad that it seems to be gone during my test drive after the ecu reset. I will find out tomorrow morning on my drive into work during rush hour traffic.....

 

So I gotta funny story to share.. I work nights and it's 445 am and I just got home.. I start looking for a ranch to take the neg off and I can't find one.. Tried like 4 different things since I didn't have my tools and nothing.. Looked in my trunk and Infiniti makes a ranch that goes in ur trunk where ur spare tire is... Never seen this before.. I know some of u are like what a dumba** but yeah so I did it and it worked... I was so happy that reseting the ecu solved that
Problem.. Now I gotta question the only weird thing that I saw was that now my windows won't go up all the way automatically if u press up to the second click.. Is there any way to fix this..?? I mean I don't really care but it would be nice to fix it.. And thanks again for posting it.. This was a really big deal for me

 

Never mind on the window thing.. I figured out how To fix it. All u do is Turn ur car off, then turn tHe key to the on position without turning ur car on.. Meaning don't put ur foot on the break, then roll ur Windows all the way down. After the are Down roll all 4 windows half way up and stop for 5 seconds, then roll them up the rest of the way and when they are all the way up keep holding the up position on the window botton for 7 seconds and that should fix ur problem. Good luck

 

UPDATE: I hate to say this but during my drive to work this morning the hesitation came back!!!! Looks like I will be hitting up the stealership and see if they can do the TSB that blueslate posted up.

 

The fact that it was cured once you reset the ECU and came back after the car relearned your driving habits means its an ecu issue for sure where it perhaps is not allowing for the BF valves to function correctly once its relearned. Hopefully the TSB takes care of it, keep us posted.

 

is that what that damn dinky little peice of metal is for? I honestly never knew! Learn something everyday. i have taken it out too look at but I could never figure it out.
