New Turbo Misfiring @2900-3200 rpm
New Turbo Cab with 500 miles. Has anyone else felt a misfire/hiccup when cruising around 3000 rpm's?? It feels like the engine has a split second pause, not a steady purr as you would expect. Had it in for service and dealer sent memo of to PCNA who responded it was normal. That's hard for me to believe. Anyone else feel this on their Turbo engine? I can't believe this is normal.

It's normal, that's the Vario-Cam at work.
I think it's an ECU event instead of a VarioCam change.

If you accelerate slowly at light throttle openings the intake cam advances at about 3200 RPM, and the high lift kicks in at about 3600. If you are cruising with light throttle opening between 1200 - 3500 RPM and open the throttle, first the cam advances, then the high lift lobe kicks in.

WOW !
I have a new Turbo Cab with 200 miles on it that does EXACTLY the same thing. I never even thought to ask, it seemed like such a minor thing that I thought the burp ( that's what it feels like) was something like a bubble in the fuel

I had it in my 2000, 2002 C2's and my Turbo.
The funny thing is, I never even noticed it until I started reading these posts on these forums.
Some people really ***** about it, and that surprises me. It seems so minor to me.
