I bought a used 2006 is250 a few weeks back and didn't have problems with it until about a week or two ago.
The car is in good condition, everything is satisfactory but when ever I drive around in a city where I have to
repeat stop and go the car occasionally make a 'fan-like noise'. It definitly comes from the engine room and It is quite loud and annoying and I can't seem to find out what's wrong with it. It can also be experieced when I try to change gears often.
I also noticed sometimes along with the loud fan-like wind noise, the rpm rises a slight bit and drops back to normal.
Can anyone help me out?
