Limp mode @ 3.5k rpm; no cel

zilent_jay · 05-04-2010, 08:33 PM

I got the car back, so the break-in on the new engine begins.

So far, everything is fine with the swap... got my low end torque back..... Will monitor for the same oil consumption issue...

Hope its fixed for you mate.

Mines done about 900 miles since the replacement sprocket, so im going to check the oil usage at 1000 miles, see if mines got a drinking problem.

Turns out I have the exact same problem. Car is bucking during acceleration... lucky if I can get it up to 40mph without the engine bucking like a horse and slowing down to 10-20mph. I'm at the stage where the sprocket is being replaced. I'm expecting even if this does solve the short-term problem... odds are I have the oil consumption problem. Oil was abnormally low when I brought it in. Still under powertrain warrantl so it sounds like I too may be forced to swap out the engine on a 2009 370z. This is crazy... not even 3 years old!
