Cant rev high

[Ironmb]

After driving about 20 miles and pulled into a parking spot a car was backing up and i gave it some gas to avoid it backing up into me. I noticed the rev was slow to increase so i park my car and put it in neutral, tried to rev it high, and the RPMs slowly increase.. i then tried to redline it and it literally slowly creeped up to 3.8k RPMs. I didnt want to keep redlining it because it was a packed parking lot full of people anyone else have this issue?

Motor oil was warm, figured there would be a failsafe limiter before the motor is fully warmed but i drove it for 20 miles.

No codes.
Tried same thing in first gear.
2800 miles on motor.

were you in wet/snow mode?

Doubt it. Literally just got in the car to drive, didnt hit any buttons.

That seems very weird.

Is it an auto?

I have seen a few auto cars when not in motion can't rev past a certain 3-4k range.

Does wet/snow mode have a limit on RPM's? I never noticed that. I use it pretty often in the rain and I can still get on it. The main difference I notice is just the throttle sensitivity.

As a side note, I will say that while I really like having the 4 drive modes, having them each change the throttle input/sensitivity on a manual car is a bit of a PITA. It's like you have to relearn your clutch/gas interaction.

OP, any codes? Could it be limp mode?

Well yea, it limits how wide the throttle body opens so the engine feels like hard to rev.

Your car must be an automatic.

when you're in park/neutral you cant crank it like a manual to the limiter. Its part of the design.

Its a manual ....

The ECU won't let you rev the engine with no load. It's normal.

Pretty sure mine cranks all the way up. I've never noticed it cutting off early.
