Thanks. Air filters and spark plugs were changed recently during routine maintenance, and the oil change was done at the same time. Your similar issue: was it fuel system related, or something else?

It turned out to be a loose connection in the fuel injection system, which caused all sorts of problems. The shop identified the defective cable quickly. I suggest having a professional take a look to confirm. Best not to mess with the fuel system yourself if you aren't sure; it could be dangerous.

Appreciate the advice. I'll take it to the workshop and mention a possible faulty connection. Hopefully, it's a simple fix. Thanks again!

That sounds familiar. I had a similar problem with my Mercedes, though mine is a diesel. The symptoms are pretty much the same: rough idling and reduced power. Have you checked the basics, like air filters and spark plugs? It could be something simple before digging into the fuel injection system. Also, when was the last oil change?
