Throttle stuttering?

Vinny · 06-28-2010, 09:15 AM

Hey guys, I noticed this morning, on my way to work, that when I give about half throttle or more, my revs stutter at around 5-6k rpms.
Not sure what this could be, any ideas? My mods are: injen intakes, stillen CBE.
Just to make sure you guys know what I'm talking about, the engine sounds like it's bouncing off the redline at around 5k rpms, but then keeps climbing.
Thanks

That's weird. When you're going back home or something, if the car is still doing that. Disconnect the battery for a few minutes and try it again.

Could be bad gas too....

Which gas station do you fill up at?

I always go to the Petro behind gallerie-des-source. never had any problems.

Yeah, thought about the bad gas issue, but wouldn't I have problems all around the band, instead of at a specific point? (5k rpm)?

Ok.. So I'm back in the car now, and the problem has mysteriously dissapeared.. Hoping it stays this way, but still curious to know what it could have been.
The mechanic at Nissan said it could have been caused by my aftermarket intakes being wet/humid or my motor running too lean because of the bolt-ons.
Your thoughts?

Update: my service oil and service filter warnings just popped up at the same time. Could it be coincidence? I'm due for service in July, orwhen I reach 29k km (which I haven't)
