That’s a valid point, everettzachary. Each engine is different, but it’s always prudent to investigate why it’s lower than expected.
Maybe it just wants to take a nap. 
But on a serious note, I had a similar RPM issue, and it turned out to be a simple adjustment in the throttle position sensor.
I’ve seen a lot of engines idle around 500 RPM, but it can be low for some setups. Have you thought about checking your idle air control valve? Sometimes cleaning or adjusting it can make a huge difference!

I definitely agree! Also, if you have an engine control unit (ECU), you might be able to reprogram those settings to increase the idle speed.』
Is 500 RPM your normal idle speed? I’ve heard it can vary quite a bit depending on the engine make and model. For some, it might even be too low. Explore if other users have similar experience!

I think it’s worth experimenting with the throttle position sensor (TPS) too. Sometimes a little adjustment can raise your idle by a lot. Good luck!
It definitely feels low! Honestly, while 500 RPM may be okay for some, if it feels rough, tuning could be a great option.

Have you checked for any vacuum leaks? Even a small one can cause a drop in idle. Fixing that might stabilize your RPM without needing big modifications.
That’s a solid point! Sometimes the simplest fixes lead to the best results. Glad you brought that up!
What if increasing the RPM just masks a deeper issue? It’s crucial to find the root cause of the low idle before making adjustments, right?
True, but sometimes you need a band-aid solution while diagnosing the issue. Plus, it could improve driveability in the meantime!
I used to think my idle RPM was low too! Adjusting the ECU saved the day. Just remember, you can always adjust back if needed. What a journey!
