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?

 

I don't think our ecu let's us rev past 5k on idling. It cuts off the fuel when you do that and is highly not recommended. Might mess up the VVELs

 

Nope.

Try resetting the ECU.

My car did this more than once.

Reset the ECU and it went away for me.

Try it out bro before taking off everything and goin to the dealer.

 

Previously it went through the entire powerband, no issue whatsoever.

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.

 

Awesome, i will give it a shot. Did you ever figure out what the cause was? Or why it was actually doing it?

 

Back then when i was working on my car i forgot to plug my MAF back on the intake and started the car. It threw a cel right away and the engine was sputtering even at low rpm. Then I did the ecu reset via gas pedal and it cleared the cel and ran fine.

 

That's weird, well i will try the reset tonight, hopefully this is the problem and i can just get an oil change at the dealer tomorrow..lol.

 

Nope never found out what the problem was man.

Have fun doing the little toe tappity tappity with the reset.

 

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?

 

Nice.

Weird, but nice.

Nah dont even mention it to the dealer they might try and figure out what caused it and blame it on your mods or something.

 

Yeah dealer wont do **** if they cant recreate the problem.

 

That is a fact!
Would the fuel pump weaknes throw any lights? Probably not if it still delivers most but not all fuel?

 

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?

 

Bolded for importance......

I assume driving the car would put the car "under load", so I dont think what you posted would apply.

Here, you could be correct. But it doesnt explain why it happened when the car was under load the first time.
