Lately I've been noticing that sometimes when im driving, and give the car about 80-90% throttle it acts like the rev limiter kicks in. It doesn't do it all the time just some times. Any possible causes? Could i be running out of fuel? I know i need a tune but haven't been able to get one yet. Thanks in advanced.

 

Sounds like an intermittent MAF issue. Codes?

 

I haven't checked, but the check engine light isn't on.

Also it seems to do it mostly after the car has warmed up and its cold outside.

 

Every MAF i've had go out never tripped the light.

 

I've never heard of a MAFS tripping a light unless it's a complete short/dead

 

I just recently replaced it about 12-15,000 miles ago. They die that fast?

 

Any part can fail at any time.

Most MAF's fail sooner than they should due to air filter oil (K&N for example) . Others just because it's a cheaply manufactured part in China, because many aftermarket parts don't have the best quality control, so it's a roll of the dice on how long it will actually last under normal operating conditions.

 

Nmex you been hiding brudder!

It's a genuine nissan part, i bought it from the dealer and i have an AEM dry flow filter. So idk

 

When you say like it hits a rev limiter does it stop increasing in the RPMs but hold a steady RPM, does it just fall back to an idle....?

 

It bounces just like you hit the rev limiter, until i shift to the next gear. I just got back from driving it earlier, and i was playing around and it didn't do it so????????

 

I wonder if your tach is inaccurate and you are hitting a rev limiter

 

That would be easy enough to check if you have something like Torque Pro or Dash Command. Just pull the RPM's from your ECU.

 

Good thinking boys!
