10,000RPM? Hard to believe.
Our reference doesn't show a P0175. I have found a number of mentions of this code in conjunction with a P0172. This means the air/fuel ratio is too rich. Check the fuel pressure. Check for a clogged air filter. Check the gap on the spark plugs(.039) and the plug wire impedance. MBZ doesn't supply shops with a specification for this, but expect in the range of 14Kohms to 20Kohms.
