you must have pumped some diesel after a party....
Any malfunction of the electronic equipment would bringup the dashboard lights. It sounds like your intake sensors but it isn't since there is no fault light. I'm afraid I is coming from the mechanical side. You have mentioned reving your car over 5000 rpm, how far over did it go previously?

It was just today that it happened, and it was during heavy acceleration.
It was initially stuck at 4k, would not go above and the car would sputter pretty bad, almost as if i kept dropping the clutch.
Then like i said i pulled over and *not under load* tried to just rev it up, and it wouldn't pass 5k..
But yea, not CEL's at all.. Slip came on when it was sputtering hard though.

Ok, so i finally got home from work.
I tried to reset the ecu using the pedals.. and had no luck. I tried about 20 times, lol i guess i just don't have the timing right.
So i got a little frustrated and just started the car... Let it warm up for about 10-15 minutes, and said to myself... "Maybe it just went away"
Sure enough, i drive out of my driveway and have no problems... rev hard through second, nothing. So i take it on the highway... Redline through 4th...
No problem??? What the hell?? where did it go, was it maybe that i wasn't warmed up this morning (80degrees)? Should i still re set the ecu?
Also could i ask the dealer to re set the ecu or is that a bad idea?

On some of the 09's an updated ECU reprogram is necessary to widen the peramiters of the mass air flow readings. They were set too close and can cause diveabilty issues and not couse a light to come on. It will however set a dtc in the ECU as a past failure but still will need a reprogram. Cycling the key usually makes the issue go away but it will deffenetly return if you dont get the reprogram done. Not sure if this is whats happening to yours but sure sounds like it.

Don't want to be a fun buster, but reving a VVEL is extremely hard on the
actuator motor and entire valve train. Nissan built in a safety measure..."when
racing the engine up to 4,000rpm or more under no load conditrion, the engine will
enter the fuel cut mode." That is more than likely what you experienced.
The bigger question is what/how much permanent damage has been done to
your valve train by "spinning it up" while not under load?

So i pulled over and tried to rev it above 5k. It got there and just would not pass 5k, so i kept the pedal floored and finally it broke above. Then i revved it a couple more times and it seemed like everything was fine.
Nope, got back on the road and tried going above 4k and stutters again...
Any help would be greatly appreciated.. I would hate to have to take off the exhaust and inatake and head to the dealer...
