I was driving today around town, car ran fine, plenty of power, even off the line. THEN, I went on an on-ramp to the freeway, and it was a whole different story. Absolutely no power.
I took it back to my Mechanic, he check it out quickly (till he could look at it closer), and now suspects it might be the catalytic converter Mercedes installed, or a problem with the turbo boost.
I will take it in earlier(tomorrow) any advice. How common is it for a catalytic converter to go out/get clogged? The trap oxidizer they replaced worked fine, AND it was warrantied by M.B. I don't think MB warranties the conversion. Am I correct?
