88red4cyl Posted July 7, 2008 Report Share Posted July 7, 2008 This is on my 99 LTZ.. I ran an errand in it this evening, and I had the windows down because it was nice out.. I get back home, and I wanted to see how the exhaust sounded when I revved it (I was thinking about a thread I had read on here actually).. So I'm sitting there in the driveway, and I start revving it and it sounded good.. I decided to give it some more gas, and when it started approaching 4,000 RPM, the car just started shaking like crazy and it wouldn't rev any higher.. Thinking WTF, I revved it again.. Same thing happened, felt like the engine was stumbling really bad or something and the car shook.. Is there some sort of rev limiter for when it's not in Drive, or is something a miss? I didn't get any SES lights or anything, so I thought I'd see what you all thought.. Quote Link to comment Share on other sites More sharing options...
1990lumina Posted July 7, 2008 Report Share Posted July 7, 2008 That's the rev limiter. Only lets you go to 4000rpm in park. Pop it in neutral to rev to fuel cut. Quote Link to comment Share on other sites More sharing options...

I was actually kind of hoping that there was something wrong that was making it do that though.. I still haven't been able to solve the fuel mileage issue on this car, and I was hoping this would help me.. Oh well. Quote Link to comment Share on other sites More sharing options...

Oh well. believe me, i have been there before.....dad showed me on all the cars the rev limiter.....you could always just brake torque it and see how high it goes, that 3.8 should be able to break the tires.....

You my friend, have an issue with your P/N safety switch If the car is in park or neutral, it will not rev past the limiter Quote Link to comment Share on other sites More sharing options...
