Maintenance/Repairs

Hi guys.
I have a Hyundai Accent 2012 with 62k miles, 1.6L engine.

I am having an issue, maybe you can give me some clues on what to check tomorrow, i will be doing some maintenance removing and cleaning up the throttle body passage and butterfly with cleaning spray.

The issue i am having is

1. the car randomly stalls at lights. This is the reason i want to start cleaning the throttle body.

2. Sometimes when starting the engine, RPMs are high but the tachometer needle does not register anything while the engine vibrates like if it was missing a cylinder. I turn it off, then start again and the car will start absolutely normal showing the RPMs in the tach around steady 800.

RPMs idling is steady, not going up and down and i do not have an issue like sticky accelerator or anything like that.

There is also a clean dashboard, NO check engine light, so i have no error codes to give me a clue about what is causing the issue.

What else should i check while i work on the intake section doing the clean up?

Thank you for any tips.
