I have a Toyota Vitz 2005. Getting two problems:
1. The car drops RPM and my car vibrates in low speed or in standing position.

2. I get a rattling sound in low speed.

Do you
have the same problem?

Is the check engine light on? Has the car been doing this for a while? When did it start?

No engine light. Its been happening for over two months. I got spark plug, engine oil, filters, ATF Fluid, etc. Changed but to no avail. Can it be related to CAT? The Toyota guys removed it. A local mechanic told me that I need to get it re-programmed or something, to adjust voltage after the removal of CAT? Is it a valid suggestion?
