I recently did a motor install myself with an 87 560sel. All went well, but my idle is very rough now. I am no mechanic, but I can swap a part you could say. I have ordered a manual for this car, but it hasnt arrived. Does anyone have a vacuum line diagram a little better than the small sticker on the radiator support they could email to me? I believe this is where the problem is at. I am not sure if I have those lines correct after the install.
