engine stutter
hello fellow v35 enthusiasts... i have an '03 g35c 6 speed. whenever i gun the car up to redline in 2nd to 3rd or 3rd to 4th gear, the engine seems to stutter around 5.5k rpm. the needle does not climb smoothly but with short abrupt stops as if the VDC trips. i've tried free-revving and there is no problem at all... i've also gunned the car with VDC on and off.. however the outcomes are both the same. the slip light does not blink at all. i really don't know what is going on...
anyone else have the same problem?... or ever heard of such a problem? if all fails, i will have to visit the dealersip.

Re: engine stutter
It could possibly be a slight misfire? Maybe a coil pack or spark plug issue on one of the cylinders or something, free revving wouldn't put load on the motor, so it may just be something that happens under load. Have you possibly gotten a bad tank of gas recently?

thanks for the replies!
i've resetted the ecu 3 times and tried again... still the same outcome.
no.. i haven't added any bad gas. I'm very **** with gas.. i only use Chevron or Mobil premium. maybe the abrupt stops have something to do with the knock sensor.. how can i sense a knock/ping from within the cockpit?

Resetting the ECU may not change anything. If a part is bad or something mechanical is causing a misfire, then resetting the ecu wouldn't make a difference. With the car still being under factory warranty I'd probalby look into taking it into a dealer and have them hook up a consult to the car and make sure it's not throwing any codes, yet not turning on the CEL. They can also check out the main sensors (TPS, etc..) and make sure none of them have a glitch or something like that.
