1999 230 kompressor
P0-170 code

I have just been giving a 1999 230 kompressor. The car is like new and after driving it for about 6 months the check engine light came on. I checked it with my obdII and got a p 107 code. After some checking most think it is the MAF. After clearing the code I proceeded to see what would cause the light to come on. If I run the RPM over 4000 the engine sounds like it is hitting the rev limiter. and the light comes on after a short time. If I clear the light, and drive it under 3000 rpm, the car will go for about 250 miles and the light will just come on. I pulled the MAF and cleaned it with carb cleaner, but did not seem to make any difference.
Before spending the money chasing problems, then finding out it was something else I though I would try the forums for some possible expert advice. Anyone out there have a similar experience and what fixed the problem.

Thanks in advance....

Pretty sure that's what your looking at. Would suggest taking apart the hose and pipe that leads from the intercooler to the MAF and look for oily residue. Also check the oil separator box and tubing that comes from it to the air filter box. The oil separator is a heel shaped black box that bolts to the valve cover on passenger side. If siginficant oil has made it's way into the air intake duct work you might want to clean it out before you put a new MAF in or the oil will just coat the new sensor and foul it before too long. (There is a hard to get to pcv and tubing under the intake manifold that can plug up in high milage 230's but that's another story) Autohaus AZ has the Bosch MAF at a reasonable price. Some have reported that cheaper off brands don't work as well as the Bosch in our cars.
