Donnie (or anyone)
I was driving my daughter to school yesterday and my 1988 300E seemed to jump a little when switching gears (automatic) and then I started feeling vibrations. I can't decipher if they are coming from the engine or from the tires. I've been told it could be transmission, wheel alignment, or just some bad plugs. I do need an oil change (2K over), do you think that's the culprit??? Please help!!
