02silverpathy Posted February 24, 2010 Share Posted February 24, 2010 My VQ (67K) has been doing something for a while now, however it is starting to get more frequent. While in drive, stopped, the idle is fine at 650-750 RPM. Truck fully warmed up, etc. Then for a few turns of the engine it drops to 600-650 and feels like its grinding through the steering wheel and brake pedal...almost lopy as if a cam were installed. Then returns to normal for several moments again. I would say if I were to be stopped for a total of 5 minutes, in drive, the truck will pull this weird event every 2 minutes?? I have also heard this lopy idle happen while its idling not in drive, but can't tell how it felt as I was not in it. I have a Chevy buddy that heard this happen and actually asked if I had changed timing or done other work to the engine as the lope for those few seconds makes it sound more like a V8. Any ideas out there? Link to comment Share on other sites More sharing options...
Kingman Posted February 24, 2010 Share Posted February 24, 2010 These VQ engines run off of coil packs and ignition modules right? If so I'd look into one of those starting to go away... Link to comment Share on other sites More sharing options...
02silverpathy Posted February 24, 2010 Author Share Posted February 24, 2010 Sounds right, but with no codes all shots are in the dark with regards to replacing yes? Anything else? Link to comment Share on other sites More sharing options...
01silvapathy Posted February 24, 2010 Share Posted February 24, 2010 I knida have the same thing. Like esp when turning into a parking space, or coming to a stop before turning onto a street. Kinda feels wierd and the rpm drops but I dunno whats doing it? Link to comment Share on other sites More sharing options...
180sx Posted February 25, 2010 Share Posted February 25, 2010 It's an early model VQ (besides the Maxima) so I wouldn't worry about it. But that's me. Otherwise I would change your fuel filter. Good place to start. Link to comment Share on other sites More sharing options...
02silverpathy Posted February 25, 2010 Author Share Posted February 25, 2010 I thought the same thing about the fuel filter. Kruddy part is I just changed it 7K ago. I know tons of stuff about changing them often, but I think once a year is often! Link to comment Share on other sites More sharing options...

02silverpathy Posted April 2, 2010 Author Share Posted April 2, 2010 Found the problem...super simple. I had a vacuum leak in my intake piping....that's it. I had also triggered a P0170 lean right bank code, that has yet to some back. The truck had been parked idling for ever in a driveway with the rear end higher than the front by about an " difference, this could have contributed also as the fan was only pulling "x" amount of cool air.
