If my car is idiling and i rev it and hold it at roughly 2k it unleashes an army of white smoke, above that it burns fine. I m guessing its the o2 sensor and carbon buildup, since i do have some carbon buildup. which can be seen by looking at my muffler which is all black in the tip. Any body no whats going on?

White smoke = burning coolant no?

Thats what I was told anyway.

Is this a newly purchased car?

When I bought my 240, it had sat for awhile and it was creating white smoke really bad…

Then I did an oil change and sat there with it rev’d up to about 3000 rpm for about 15 mins and that did the trick.
