I drove it to a store and when I got back in, I did that again - don’t know what the heck I’m doing 🙂. Then drove home. It was was smooth and accelerated normally.

What does that tell you?
The detente is almost like a click of a button at the very end of a full wide open throttle (WOT), slamming the gas pedal to the ground. When the pedal is on the floor, you can feel a "click".

I didn’t notice that. Was I doing it correctly? Should I hold it there? And why would that seemingly help the problem I was having? Am I supposed to be doing this before I start the car? Because that’s what I did.

The click/detent is definitely there. It's just before the pedal is as far as it will go. Try doing it slower/smoother.

Why did it fix the problem? Because I'm a genius and you're magical! Nah, it probably just dislodged whatever was in there... or at least moved it to a different spot and it will reappear at a later time

Okay. I’ll try again tomorrow. I’ve been so thrilled with how well it’s driving I was ready for a road trip. 😉. I’ll have my mechanic look at it when I’m back again next month.

Thank you again. Y’all have become my new best friends.

Now just one GL450 with EORP.
Best thread ever, because it’s not something we see that often. 90% of posts seem to be about why is my left wheel sagging down, should I change my valve block. We thank you for your eloquence and responsiveness.

FWIW... If you have the after market slide on AMG pedals (chrome looking with black rubber knobs) the detente sometimes won't engage. Mine does not. 2010 GL550
