you sure VDC didnt kick on when you "punched" it? That will cut power for a good second or two and could have been the delay you experienced.

I almost always turn VDC off, its annoying.

 

I agree with Wannabe, try another car if you don't have the luxury of an ECU reset/some aggressive driving to teach the TCM.

 

Thanks for all of the responses so far. Like I said, I have driven many automatic cars before, so I know there is a usual delay, but this delay was abnormaly long. I am talking about the throttle response, not the gear shifting.


I am going to go test drive another one to see if the problem was just with the one car. How do you turn off the VDC? I heard there was a switch on the steering column, but where and what does it look like?

 

I felt the delay a bit also, my old car took right off as soon as you press the pedal. The G was a bit delayed for me, but im pretty sure this is normal.

 

Its right next to the trunk open button I believe. With the vdc off the car feels and accelerates faster. Test it with the vdc off and let us know what u think

 

IGN's review on the vdc

Today we decided to give the G35 a spin with the VDC off. Well, one this is for sure--VDC rocks, but that's a given. What we did notice is that the G35 reacts and handles totally different with the Vehicle Dynamic Control off. It's like two entirely different vehicles.
On one end you have a very refined, very neutral car. Hit the throttle in a patch of wet and it'll spin, sure, but it won't get nutty. Between the VDC and LSD the G35 will compensate for the power to the ground and give you a safe almost worry-free feeling. It really tries its best to make sure that the car stays parallel with the road you're on. Take a corner too hard and the G35 WILL do everything in its power to keep you safe and ready for anything ahead. The car comes to a near halt when it senses too much motion.

However, take the VDC off and the car feels spryer, squirrelier--in a way. With VDC off hard launches are met with a bit of sideways action not unlike the cars at the drag strip. In fact, in wet the twist from the rear is so much that you'll immediately want to lift your right foot off the pedal. Take a turn too fast and you will see the rear end swing around. But we must admit that we do love seeing the G35's real character come to life. Hard launches on dry will be met with some slippage, but it will feel like the 260 horses that Infiniti left under the hood.

It's nice to know that the G35 is capable of twisting and turning like some of the track cars we have tested. Now the thing is, most won't want this civilized sedan going agro, but it can if you like. How does the Nissan adage go? "Not that you would, but you could?" So this G35 does prove to have a little bit of Mr.Hyde for its Dr.Jekyll.

We must be honest, however. Unless you plan on turning the G35 into a legitimate track car, you should always keep the VDC on--especially in rainy conditions. It may not feel the way you want it to, but it will feel much more solid in the sense that you don't have to worry about stomping on the throttle and being met with the side-to-side shimmy. Hmm, VDC-off with that optional manual tranny, now we're talkin'!

The VDC button should be called Sport Mode!

 

I've always found the G/Z's drive-by-wire throttle one of the most responsive DBW setups I've ever driven and I rent tons of cars/trucks/SUVs for work. The throttle delay on that particular G could be related to the fact that it's an X which comes with a deeper gear set and it may be Nissan's way of reduce initial throttle snap. It could also be that the dealer had 87 octane in it vs 91+. The TB, MAF, and/or throttle body could be a bit dirty as well. A well running first gen G, auto or manual, should be pretty snappy.

 

UPDATE: I drove another one today and wow, what a difference! There was something definitely wrong with the first car that I drove.

The one I drove today had much better response and acceleration. I turned off the VDC and it was even better.

Thanks for all the help! I hope to be a new G35 owner soon.

 

i have a 2006 sedan with 25k miles i got a few months ago and i have the same lag

when i turn the vdc off its not as bad but still there

iam thinking about reseting the ECU

 

reset the ECU

 

Get rid of the pop charger and get a MD spacer and you'll forget about any lag!!

 

going to try to reset the ECU tomorrow..

MD spacer is on the TO DO list =)

so if i switch back to a stock airbox the car will run better?

 

A common belief on here is that pop chargers are affected by heat soak, therefore causing a loss of power due to hot air being introduced into the plenum. I have never used one so I can't give you a definitive answer. Most say either a Stillen airbox, or a stock airbox from the revup engine with drop-in air filter are your best options for power, not necessarily sound.

 

thanks for the info... after doing a few searches i think iam going to go with a rev up air box and a good air filter =)
