I believe with turning the SRM system off while running the car for a few mile then turning it back on will help trouble shoot the issue. For sure I know it is an SRM issue like I stated before. I didnt see that you were at zero mph earlier and after watching the video again I see that. turn off the SRM drive it and see if that fixes the issue, then turn it back on and see if it continues. if that doesnt work unplug the battery for several minutes to let everything die down and then plug the battery back up and try again.

This is problem shooting 101... Now you say you arent worried but man seriously you should hear your voice in that video. Im not meaning to sound like a prick or an A$$hole but you sound so worried and like a little b!tch. I dont mean to be rude but take a step out and realize its a machine it may have problems and its not doing it to you on purpose. Its not bad luck either and if the problem persists take it to the dealer this is not that big of a deal! and this coming from 1 of 2 on these forums that has blown a stock motor already! I blew my motor at 10,100 miles and 1/2 mile from the dealership cause the motor was making funny noises. My car has been in more shops for over 6 months than it has been on the road. Just relax and take another video without the "why is this happening to me" attitude... Thanks and we all want to see you enjoying your Z so try these trouble shooting ideas before you shoot them down.

Bullit, it's just that I've spent 2 months bringing my FX back and forth from the dealer for the same thing. The FX has now been gone for well over a week. That's why I'm ticked. I should be. I spend more of my free time running these cars to the dealer than I have time for. The Infiniti dealer is over 45 minutes for my house, 1 way, and has been in 4 times for the same nav screen thing because Infiniti told the dealer NOT to put in a new screen. I'm sorry. 5 because the first one was a diagnosis. Not to mention the problem with my XM radio (9 hours of total time to get that straightened out) since they replaced the AV unit (used from California. Nice. His name was Mark), dead steering column, loose center console, a screw caught rolling around in the hatch door that they can't find, Bridgestone tires that had to all be replaced because they were loosing huge chunks of tread, a transmission that had to be reprogrammed for huge flares and thuds, and to cap it all off... The tech accidently banged my door into the metal rack. Now the door is being repainted. Get it? The car has been in 14 times in the past year for things OTHER than oil changes. (And it's not me being a whiney owner. Chunks of my tires were coming off and I could hear them smacking the wheel wells.) Of course I'm bothered. The FX is still in the shop, now I have to bring this thing in. That's gas money and time I'd like back. 14 trips= 1120 miles, 26 hours not including traffic. That's just the FX.

The Z has only been in once for the oil changes, grinding second gear, and that high pitched noise. Luckily that dealer is only 20 minutes from me.

Of course I'm bothered. While the Infin was in, I thought I'd enjoy the Z. I did, it just broke and wanted to show you. Next time I'll just not say anything and you can figure out what wrong and how I feel about it. Calm down Bullit. I'm just sharing the information.

Oh, the FX is a 2009 35 with 15,000 miles on it.

I respect all of you who haven't bashed me for just posting a video. I just wanted to share and ask what you thought before I bring it in to the dealer. Thought it would be a fun discussion.

HKYStormFront · 01-29-2010, 10:11 AM

chalk me up in the group that says take it to the dealer and let them figure it out. probably just a hard reset on the ECU to relearn the parameters. just post what they find and then we'll all know...

bullitt5897 · 01-29-2010, 10:55 AM

TW, Im not bashing you bro. not in the least bit. Its harder for us to watch videos when people are complaining and it often gets a negative connotation associated with it when you do that. Like I said I didnt want to sound like an a$$ for saying that stuff its just that type of tone and stuff bugs the sh1t out of me and especially someone asking for help. You know its like a hey dude calm down kind of thing.

I understand the dealership deal. I believe you just have a sh1tty service dept. at the dealer to be honest. It should not have taken that long to fix those kinds of problems and to still be dealing with them. If it were me I would sit down with the service manager and have a lil talk. For instance the dealer put my z on a lift wrong and put a small bend in my side skirts. I saw it and talked to the manager and now I am getting free nismo ones. They should atleast be compensating you at the very least. I hate to hear what is going on with your FX but I will say this... that is a completely different platform and should be kept separate from the Z. I hope you have a Nissan dealer closer to you and be upfront with them with I want a no nonsense fix for this like yesterday. It always works for me but then again I call the shops and talk to them every other day to get status updates. It may seem like alot of work but I know my stuff is getting done correctly. I also talk to the techs that work on my car personally and if I dont like them I ask for another tech. Remember you are the customer get what you want!

Again, nobody is bashing you for posting the video. In fact we encourage you to do it when you have problems, as it helps us to help you. Please keep us updated on the trouble shooting and hopefully we can help you solve the issue without you having to drive to the dealer.

your a good guy keep posting!

TheWeatherman · 01-29-2010, 11:03 AM

It's fine Bullitt. It was just frustration that's been building up. The reason I bought two Nissan products is the fact that I've had nothing but luck with the brand. It's like the complete opposite side of the spectrum from my previous models! Suprising! I'll keep ya updated though.

I'm treating it like a "let's take a stab at what's wrong." The correct guess will win... A post from me talking about what was wrong!

I just find it fun. I was a little annoyed in the video. I was just "thinking out loud" in the video. I work in TV, so I'm used to just talking to noone. Wait, is that a problem?

bullitt5897 · 01-29-2010, 11:14 AM

Ladies and gentleman the weatherman is confirmed as crazy!

lol

spearfish25 · 01-29-2010, 04:38 PM

Keep us posted on the resolution.

I find this issue a bit disturbing 1) with the Toyota recall ongoing and 2) with the fact that my wife would not be well suited to dealing with this issue if she's behind the wheel. If the revs climbed like that on her, I'd guess she'd end up in another guy's bumper or in a ditch. You guys with 7ATs should be a bit concerned too. It's a no brainer going to neutral or clutching if the revs go bonkers in the 6MT. You'll have to have some quick thinking if it does it to you in the 7AT.

I dunno. That was the first thing I thought of (put it in neutral) when something similar happened in my Mustang (gas pedal got stuck on the floor mat). I put that bad boy in neutral right quick!

But then I'm kinda weird in that I think about emergency situations beforehand, such as when I'm about to cross a bridge, I think briefly about how I would escape from my car if it plunged into the water.

Yeah.

TheWeatherman, I asked the following just to make sure it's NOT the SRM that's causing this. Though, after watching your video again, I find it VERY bizarre and I blame a faulty accelerator pedal assembly. (possibly). But, I'm still curious, were you able to replicate the above mentioned problem without SRM?

Here is why:

first of all you are in sport mode which enables synchro rev match. Secondly you pulled the transmission out of gear and left it in neutral from 5th gear. The way synchro rev match works is that it anticipates your next gear so for instance if I were to shift from 5th to 4th it would rev for 4th gear's rpms. Now SRM (synchro rev match) only revs when in neutral or at the gate of the next lowest gear. That is your problem... well not a problem just a lil uneducated on the feature. If this bothers you turn off your SRM by pushing the sport button until the little S disappears from your gear indicator. This has nothing to do with your car being warm. Now if you want to try it again leave it in gear this time and just clutch it... I bet you it wont do the rev climb.

So in final your Z is perfectly normal... so stop babying it and drive it like a big boy

Very weird /\..

Then when I actually start moving from neutral to a gear it will lock onto the actual RPM it needs for that gear ratio which may cause it to rev up a little higher still in the case of 1, 3, 5. In neutral it only does this for about 2 seconds before it gives up on you.

I've seen other people documenting this behavior, including a video so I know I'm not crazy.

I will clear up some confusion with a video that I made yesterday. I don't know why Modshack's SRM doesn't do this but almost all members here can say the same thing about neutral drop with SRM on. Bullit, Chrislicks, M41mustang - I think this is EXACTLY what you guys are trying to explain. Take a look

(sorry for the cheesy forum advertisement at the end

. I usually get tons of questions in comments section so I explained everything on the video)

As you can see, if I move the shifter from 6th to Neutral, RPM goes up( just enough for 5th gear) and stays there until I pop it to 5th. BUT, if I move the shifter to the left (while staying in neutral), car thinks I want to downshift even further (3 or 4th gear) and REVS the RPM even more. This is a very normal behavior and as mentioned above almost ALL of the 370Z owners with SRM experience this (except modshack). Modshack, maybe this video will show you what we are trying to explain.

As for OP, sorry we kinda got a little off topic. PLEASE keep us posted on what they find out.

Wow....Personally I would find that behavior VERY annoying. I had no idea you guys were having to put up with that. If mine did that I'd most likely turn it off... Looks like Pushing Tin and I are the lucky ones out of this group...

Completely OT, but you have a good taste in music.

why not just pop the 7at into neutral? that's the thing that also puzzles me about all those out of control toyotas with stuck throttles. even if its automatic, it should still have a neutral position.

And you have just proven why Darwinism exists...

I have asked myself this EVERY time I heard about people dying due to a "stuck" throttle...

spearfish25 · 01-30-2010, 08:10 AM

Nice demo AK. It makes it pretty clear that Weatherman has a very different issue.

MightyBobo · 01-30-2010, 09:47 AM

OK, sorry if I missed someone recommending this, but I think you guys are over analyzing. I think its probably as simple as a throttle position sensor either being shot, or needing recalibration. There IS a recalibration method if I remember correctly, in the service manual. I dont have access to it at work, though.

MightyBobo · 01-30-2010, 10:02 AM

If you're cruising in 6th, and pop it into neutral (actually letting go of the stock), it will automatically blip the throttle to 4th gears required RPM. It automatically assumes the "minimum amount" it needs to rev to (as in, the highest gear to choose). If you decide to go into 3rd instead, it'll rev even higher of course. Wiggle the shifter around in neutral into the 1/2 gate, and it'll rev to 2nd gear levels. I remember doing this when I was test driving - doing the neutral wiggle is a habit of mine.
