Cls 55amg running rich
I just bought a cls55amg with 37k miles. Car looks and runs great. It is white and every time I drive it even 5 miles the back bumper is covered in what looks like soot and oil drops. Any suggestions on what my be causing this or how to fix it. I think it is running rich but don't know

Thanks

how much did you pay? I am on the market also

31 k. Bought out a friends lease

Great deal! I am looking at one with 75k but buying for $25k and warranty

That doesn't sound good, I'd take it to a shop ASAP

wow, you guys are finding some very cheap examples! to a certain extent, i'm a firm believer of "you get what you pay for" and "if it sounds too good to be true, it probably it"

GL nonetheless, scan for codes and pics will help.

Is it tuned? Talk to Jerry at EC. He can lean out the part throttle maps.
