Anyone getting any black smoke on hard acceleration?
Anyone else's doing this?
Well I tried mine out this afternoon and, yes, I got a nice black cloud. I got to thinking, in "the old days" (yes, I am older than dirt) we used to have a common expression like "It needs to have the carbon blown out of it". Now this was not a factor for me when I was driving my Oldsmobile 442, as it saw redline as often as possible. Well, I'm a little older and cars have changed. I look at the Tach on the Cadenza and it always seems to be 1500-2000 RPM. My wife would not "Punch it out" if you paid her! I guess what I'm saying is that for me, I'm going to "Blow the carbon out" with some form of frequency. I'm sure there is some design feature of the GDI engine that contributes to this but I don't know how you would find this out. Let me know if you have any ideas, hopefully ones with some science behind it.
