Hey guys -

I have a 1.5T 2017 Ext 6 speed.
I noticed as I was driving around the other day in stop and go traffic, that the engine would maintain high revs or seem as if it’s reving even after going into neutral and fully lifting off the gas. It seemed to last until I came to a complete stop (fully on the brakes.)

I have the mishimoto intake installed. Let me know if anyone has experienced this quirk in their cars or if I should be concerned.

thanks

Probably a vacuum leak, check your intake install.

Also make sure your floor mat isn't on top of the accelerator pedal. Unlikely in this car I would think, but it has certainly happened in other vehicles.

Isn't this what rev hang is?

Nope. This isn’t your typical rev hang. Basically my RPMs would stay up by 3k until I came to a complete full stop. Let’s say I stayed off the brake, it would remain at 3k until I fully stepped in the brake.
