Then it will continue to rev. In the 2nd instance it got up to 3000 rpms before I put the car in 2nd gear and left the stop light. After moving the revs go back to normal. Then it happens again at the next stop light. Finally I get to my destination and turn off the car. I start the car up again about 15 minutes later and everything is back to normal.

Any ideas, suggestions? I am guessing if it doesn't happen all the time it's not that big of a deal. And if the people at Nissan can't replicate it when I take it to the dealer they won't do anything anyways.

EDIT: I guess I should have made the title more clear. Obviously it will rev while in neutral. What I meant is that the revs stayed high and continued to get higher.

Today I was driving for about 20 minutes casually, not speeding or anything strenuous. It started raining very heavily and I had to stop the car when I got home, get out and put some things in the boot of the car from the garage. I left the car running while I did this (maybe 3 minutes) and then I got back in and began to drive away.

As soon as I got onto the road and tried to put it into 2nd the car started jolting very hard back and forth, same with 3rd, and 4th. I realised it was happening any time I took it to around 3k RPM. Engine temp was fine, (below 220).

So I managed to get home anyway and it's sitting outside now, i'm waiting for it to stop raining before I go check it out.

Is this limp mode? or something else? I did do some strenuous driving last night for about an hour or so on the track but I didnt get limp mode, drove it home fine, it drove fine today, and the temp last night didnt go over like 225 ish.

Any ideas??

I turned out if the dealer parking lot and got on it a little bit in first. Thats when the problem started. As soon as i hit 2500RPM it was like i was hitting a rev limiter. So I let off and shifted into second, same thing. Came to a stop light and started to go, not to hard either. Same thing happened when i got to 2500. I shifted to second, same, and to third and was still limited. Turned onto a side street and parked. Of course the sales person I was with didnt really know what was going on or much about the car. We turned it off and back on and turned the syncro rev match on and off too and it still was limiting me to 2500RPM. We then drove back to the dealer and another sales person took the car out to test out problem. He did not encounter it. The car sat for less than 5 min between when we brought the car back and the other dealer tested that car. Im pretty sure it was sitting longer than that from the guy that test drove it before me.

Anyone else hear of or encounter anything like this?

2009 370Z Touring MT6 w/sport package

Engine Oil temp: 200 degrees or so
Water temp: two dots from center
No warning lights or indicators
No over rev lamp
Haven't tried pulling codes

So, here I am driving along from a cold start, engine oil and water temps slowly creeping up, and as I get on the freeway onramp, the engine cuts out at about 3500 rpm, car slows down, accelerator reengages at around 3000 rpm. Interesting...

So because it sounds familiar, I just row through the gears keeping the rpms below 3500, and it consistently cuts out above 3500 for the duration of the drive. Other than that everything else appears fine. I have somewhere to be, and it sounds familiar, so I just get to where I need to go.

Get back out to the car a few hours later. She starts right up and behaves as if nothing happened. I'm going to bring it into the dealer in a couple of days.

Without codes or ability to repeat the symptoms, it may be helpful to see who else has had this, and what the fix is.
