Let Rpms Get Too High!

[dbguru]

I have a 2009 IS350. I was passing in 2nd gear and missed an upshift to 3rd. I thought I had shifted, but I guess I didn't. I may have hit the cruise control thinking it was the upshift paddle since I don't use the paddles that much. Anyway, the rpms went all the way to 8. The engine started vibrating or missing. I immediately backed off and realized that I was still in 2nd. The vibrating/shaking only lasted about 2 seconds. I have two questions: 1.) what was happening when the engine felt like it was missing or vibrating? 2.) Although it seems to run fine now, did I do any permanent damage to the engine?

You hit the rev limiter. The engine was shutting down as it hit high RPM and then restarting as RPM dropped. That's what it's there for, to prevent damage from over revving.

YIKES, that must have been a little disconcerting.

Probably didn't break anything, but I'll make sure and not buy any used cars from you ;)

yep, you hit the rev limiter. No harm done, thats why its there.
