A couple of weeks ago my check engine light came on and I swapped out a few sensors with no success. I've noticed the car having a rough idle, where the RPM's isn't stable and drops suddenly then rises up again. Every couple of days it would also suddenly stall when i'm stopped.

Good morning,

Can I have the code or codes that were set in the system and the sensors you replaced?

I would start by cleaning the throttle body of all carbon as that is a very common issue for stalling.
