Hi, I have a 1992 mercedes 300se and had to change the water pump. I changed the pump and it stopped leaking anti-freeze but after I put everything together I started the car and the ASR light came on. Now the car wont got past second or third gear and it sounds like its got a vaccum leak or something when the car is runnning. I was wondering if there is anything around the water pump that I could have accidently disconnected or screwed up while working on the water pump that would cause either of these two issues. Or is there a way to turn off the ASR so the car will run normal and shift through all the gears. Any help would be greatly appreciated. Thanks, Danny
