I am posting my condensed experience on this subject to spare other 103 owners from going nuts/broke or both.
I bought this PIECE at a good price with the intention of reselling it. It had a "fresh smog certificate" and drove it 300+ miles, I loved and enjoyed the smoothness and I immediatly thought what a great grandmas car(I am a die hard mercedes diesel rattling cage fool: 74 240D 4sp).
Anyways the honeymoon stopped abruptly when the car started to show the above symptoms and all other signs of being possessed, I thoght the problem was not "BASIC" tune up related because it flew thru smog.
