Vehicle Stutter / Limp Mode?

NihonX · 11-05-2009, 03:37 PM

Hey, I was wondering if anyone else has experienced going into limp mode or a stutter whenever you redline.
It's not done intentionally but has happened a couple times where I was shifting at around 6000rpm and "accidentally" ended up at the redline in second and when I shifted to third, it would feel not only underpowered but also it would have a stutter or vibration that felt like I was riding over jagged rocks even though I was on a smooth road (Highway surface)
I have to turn off the vehicle, then on, in order to correct the problem.
I wanna guess it retards the cylinders but.. I don't know much about engines and whatnot.

Maybe I should not get so excited while driving onto an on ramp..

The fuel is cutting off to protect the engine from over revving.

Hi there

This also just happened to me today, is this just a safety feature or is it a bad thing? I thought it might be due to hot weather since it is 30 degrees celcius today..? Just to add, I was at WOT but not redline in 3rd gear and I felt a little stutter at about 5000rpm, so I backed off, then same symptoms as the first poster in all gears till I restarted my car...
I have already had my boost pipes by the turbo replaced and my car only has 3200km on it, so im just a little worried...

Thanks

if you have a BT scan your car and see what codes where given

ok I ran some tests and the error was:

29CE:
29CE misfirings, cylinder 2
Error will cause a warning light
Error is not currently present

Event 1
Odometer 3264km 2028miles
engine temperature 99.75 degrees celsius
load value for misfiring detection 98.05%
Engine speed 3328rpm
Lambda integrator group 1 33.59%

I have done about 30km since then and it seems ok, although I haven't really had a chance to drive the car hard to check properly, its been mostly driving in traffic. Any suggestions?
