For the past few days i was going to almost every mercedes benz forum and they recommended to remove or stuff a bb in a vac line, so i decide to go ahead and do that, and the results was outstanding, Lower Engine Temp 85C, Smooter Shifting (sometimes you can feel it) Dose not smoke that much, and the best part BETTER FUEL MILAGE, i est that it about 25 mpgor higher (better than my previous which is 18-20 mpg) so after a day of driving with out that EGR, my engine seem to sound a bit louder (maybe it could be a cleanfresh air that theengine is craving for 24 yearsor maybe that the engine is begining to besoot free??? IDK??[&:]) but anyways should i be concern about this sound change???

Thx
