When ever I come to a complete stop, the RPMs drop to around 500 and wants to stall. What could be the issues on this?

Hello,

This could be due to a dirty mass air flow sensor.
That sensor is located at the end of the air intake tubing, just before the air filter box.
You can service the mass air flow sensor by cleaning it. That could fix the issue.

Many times with poor idle the check engine light gets triggered.
Is your check engine light illuminated? If you retrieve the codes as it can help with the diagnostics.

I have attached the diagram for your reference.

Please let me know of any questions.
Thank you.
