I'm starting to think I need to replace my injection pump: (
I know it's a rare problem but I'm not sure where else to look. I've got a best beautiful 81 300d. It's got 125k and by the look of the rest of the car I think it's been well cared for, I even have original purchase receipt from Lubbock Texas. From the time I bought it about a month ago it's shaken like a paint shaker and I cant seem to get idle to lower enough by adjusting idle adjustment. I'm not sure what it is but it's obviously a little high and when in drive it wants to push the car almost. I've changed both fuel filters, changed injectors with another set off another car(and new heat shields, did valve adjustment, I checked injection pump timing and it's good, engine compression check showed even in all cylinders, engine mounts replaced, it also has vibration driving down highway slightly. I don't see air bubbles in the hard lines. What else can I check? I'm running out of ideas. Not my first one. I've also got a 240d and used to have a 300sd with an odometer that stopped at nearly 300k. That car ran great! I was really excited about this one. It's a beautiful car
