Car Idle High When Warm by CodeJigon(op): 11:00pm On Mar 27, 2025
I drive a 2008 Lexus rx350 with a 2gr engine
When engine is cold everything works fine but when hot 🔥 it idles a little bit above 1000 rpm and when I apply break it's as if someone pushed the car from behind

NB: it continues like this even when cold only until a take off the battery terminal for some minutes it resets everything but when I drive and it hit again it starts again

Can I get any assistance
Thanks in advance

Change your windshield and rear bumper.

The rear bumper is clogged and adding additional weight to your car when you step on the brakes.

Your windshield has also gone faulty and has stopped absorbing the external and internally generated heat, which is putting pressure on your crankshaft.

Check engine light is on, scan the car and post the code on youtube.

It looks like your throttle body is dirty clean it, and do not adjust anything

Your code suggests timing chain stretch
