Engine rpm's (help concerned)
#11
I will make sure it doesn't do that anymore, and figure out more about it.
But my main concern today is, do you think the car is ok?
This bouncing happened only one time. Do you think any damage could have occurred?
Or am I safe, just don't do it again?

"And of course if someone else drives the car, or I drive it slow, there is no problems."
The computer limits the RPM by cutting the injectors off.
If you try to floor the accelerator pedal while you are in park the computer will start limiting the RPM.
Is that the kind of behavior you are seeing when only you drive? Sounds like one heck of a steep hill, like going up the Grapevine at 75 MPH before they "fixed" it in the 1960's.

Yeah, mostly because I am the only one that drives the car. But also, everyone else who drives it doesn't stay in the fast lane or pass people, they just slow down.
So yeah my driving habits are probably to blame.
But yeah, it's a steep hill not like crazy steep driveway type of hill but, steep long freeway transitioning from city to mountain.
My automotive teacher once told me a story about a police officer that asked him why one day he was chasing someone up that same free way hill, and the bad guy was able to pull away from him going up the hill, even though the police car was more powerful, my teacher told him go up that same hill with the air conditioner off, he did and the police officer was able to go much faster. I guess the new cars know to deactivate the air compressor when at full throttle but the older cars did not, and that meant the difference of making it up that hill fast vs. slow.
So it is quite a hill, especially for a 70mph speed limit.
Every semi-takes days to go up it. lol if there is traffic in the slow lane it's because there is one or more Semi's with there flashers on.
So your saying, it's bad to rev limit, but I'm ok doing it just the once cause it's a protective feature.
And I am not one to do that on purpose.

So you have never left CA? If you want to see a hill, try I40 out of Albuquerque.
I was going down it in my '62 VW and all I could see in the rearview was a chrome bulldog, then I started hearing air tanks venting. I already had the "pedal to the metal".
It was way worse when it was US 66.
Actually older cars sometimes had a vacuum sensor on them that cut the A/C off upon acceleration. I bought an after market version for a '68 Karmann-Ghia that had A/C.
I don't think they bother anymore.
If that is what is happening, it is the computer saving the car from damage. Quit tempting fate. I think the limiter cuts in at 4,000 when in park, never tried it driving.

Well it sounds like it was completely my fault. Lesson learned.
I was driving home today with no traffic and the car was great stayed under 5000 rpm the whole day.
The car is still running great, stays cool, I will be in the slow lane going up that hill from now on. :)
