Couldn't rev past 4500rpm
Last night, in neutral, the car wouldn't rev past 4500 rpm.... it would just get to that in the rev range, and drop down with no throttle response.
Similarly, in park, it did the same thing.
I turned the car off, and back on again, and this seemed to resolve the problem.
I have a 2009 is250 awd with about 83000km on it... regular scheduled maintenance was for 82k, but I haven't gotten the chance to take it in yet.
Lately, I have been noticing some interesting things... also including when shifting from drive to neutral and back to drive, there is a couple of seconds of delay with throttle response once back in drive.
Any ideas on what this could be? MAF or throttle body related? I'm hoping its nothing transmission related
Thanks

Which I agree with, but the fact is it happened, I switched the car off, and it was "resolved"... I'm concerned because transmission repairs tend to be a PITA and take a lot of labour hours....
But at the same time, I'd like to know if there's actually a problem with the car or if it was a one-off problem. I'll try and see if I can get a reader to see if she's throwing any codes...

I will check my car later, but I am fairly certain the ECU limits the RPMs in neutral or park because it's not good for an engine to rev high when there's no load.
But regardless, if the car shifts and acts fine when you just drive it properly and leave it in gear, then I wouldn't worry about it.

This happens to me randomly sometimes. Usually I can redline and it spits fast. But sometimes for some reason it doesnt let me rev past 4500 like you're saying. Random, I never heard anyone with the same situation.
