dbguru Posted May 30, 2009 Share Posted May 30, 2009 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?

bartkat Posted May 30, 2009 Share Posted May 30, 2009 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. Quote Link to comment Share on other sites More sharing options...
Sidney07 Posted May 31, 2009 Share Posted May 31, 2009 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 ;) Quote Link to comment Share on other sites More sharing options...
