Helo,

I own Suzuki SX4 Sedan, year 2012. I noticed that my car started shaking, better say vibrating. RPM when the engine is on standing around 500-600 RPM without air conditioning. When I turn on the air conditioner RPM standing around 700-800 and then my car does not vibrate.

I wonder when I turn on the car sx4 and when the engine is warming up (after 5 minutes) how much it must have RPM ?

500-600 rpm at idle when warmed up is correct. It is OK that rpm is electronically increased when turning A/C on.
YOU did not specify if manual or auto. MIleage ? Engine type ? (depending where you live)

Thanks for your reply. My cars are automatic and have 80.000 miles.
RPM stands around 550 rpm when I stand in 'N' , 'P' or 'D' (Neutro, Parking and Drive).
When I turn on the air conditioner (I live in South America and here it is pretty hot) RPM get up to 700-800 rpm and then the vibrations disappear.

I change spark plugs, air filter and I cleaned the 'Body acceleration' or as some call it 'butterfly', I do not know what that part is called in English so I'll leave you a picture:



I checked the engine bearings and the engine bearings are fine. On the board I do not have check engine light on.

After all this, vibrations still exist :( and I really have no idea what it might be, why it vibrates.

OK...there are many engine types (diesel, 1,6...)_so OK 2.0
I can say "some" vibration can be felt at idle..but not annoying . Can you say this vibration has increased woth time?...I would check engine mounts.
YOur picture is a throttle body. It is electronically controlled.
I visited Argentina, Uruguay and Chile....lots of Suzuki products around there, several unknown in North America.

I bought my car Suzuki SX4 Sedan (year 2012, 2000cc, automatic transmission) directly from the US, means my car is US version. In idle I feel the vibration and while I drive I have no vibration.

As I said before I bought new 'spark plugs' and 'air filter' and I cleared 'throttle body' in South America it's called 'acceleration body'.
I checked 'engine mounts' or 'engine bearings' and everything is fine with them.
Normally, there was no vibration when the car was new in idle, with time appeared.
I have no idea what to do next.

I hope you have understood that engine mounts are those metal and rubber supports that attach the engine and transmission to the car body. With time rubber can desintegrate and metal to metal contact brings severe vibration to the car body.
Can you take a video and post it ?

I'm not an automechanic and because of this I can not record the video.
My automechanic is checked 'engine mounts' (sx4 owns 4 engine mounts' and all four are fine. I should say engine mounts are in good condition.
