Throttle lag
#16
Did you ever find the solution? I am having the same problem now. After driving fast, coming to a stop then trying to drive again right away it "pauses" for a second then violently jerks forward. The car is at the shops now, but they can't find the problem yet.

Did u ever figure the issue out?
Did u ever figure this out bro? Seems like I let my car idle for 10 min and then limp mode turn on off and all is well back to normal..?
I'm having this same exact issue and can't figure out what's causing it. I have an intake and exhaust installed but it's odd when it happens, if I park and turn the car off and wait a minute, it'll work like nothing happened. It's almost like limp mode without the codes and speed limiter.

Ok so i have searched up and down for a fix to this issue i cannot find one. And please spare me the "buy uprev/ecutek". This is a malfunction somewhere in the car.
But at completely random times my throttle becomes almost completely unresponsive. To me it is dangerous especially when trying to pull out and make a left, and the throttle does not respond to my inputs. My car is a 6spd so i have stalling issue to worry about. Not to mention its hard on my clutch and makes the car very difficult to drive. So i do not know if this helps narrow it down but when i come to a light the idle dips to 400-500rpm for a second or two then pops back up to 800rpm. It will also idle surge at times, just suddenly at idle rev to 2000rpm like i have blipped the throttles. I have a feeling this issue are related. While i do plan on getting either ecutek or uprev in the future. i would like to fix whatever is causing this. I've driven G37s that do not do this, so what is going on with mine?
Help?

the problem is you need a TCM update. You will have to bring it to the dealer. I just had mine done 2 weeks ago with exact same symptoms. In 2011-12 infiniti issued updates for the TCM to correct these issues. Since my update no issue and the car drives totally different. Couldnt be more happier. The dealer charged me $165.
GUYS... You're being so unhelpful, stop talking about TCMs and 7AT quirkiness... OP literally said several times he has a manual.
So OP, you scanned and got no codes, grounded the TBs and it got better, then cleaned MAF and TB, and it got even worse?
