SLK/R170: SLK 230 98 Struggling
The car is struggling in upper rpms ranges.I'm pretty sure I can hear the blower whine and the car will rev out while driving but it's down on power for sure.Seemed the more I layed the pedal down the better it got.It will rev out in gear just not smoothly and certainly not the pull it normall has.
Almost like it is not gettng full boost like it should.Idles and drives in traffic like it always has.No check lights at all.Oil is fresh but the air filter is a bit dirty.
