Hi there,
I have been facing an issue while driving: my car stalls at signals and whenever traffic is slow. This usually happens when the A/C is on. I have replaced many parts, but the issue still persists. I saw a post where you mentioned replacing the electrical system. Can you be more specific, sir? It's a big headache when the car stalls at big roundabouts. I hope you can advise.

What parts have you replaced? To me it sounds like you have a vacuum leak or a dirty throttle body.

Here is a guide to help us:

Here is how to clean the throttle body in the guide below:

If you have a check engine light on we need to know the codes. Check out the images (below). Please let us know what happens.

Did you check for vacuum leaks? Also, we should run the codes to see if there are any stored which can help guide us to the problem.
