I have a 91 mercedes benz 300SE. I just installed a used engine in very good condition and i tuned it up with all original parts ( 4 points platinum spark plugs, wire, cap, rotor, air filter, gas filter and i change oil evey 1k miles). The problem is some times NOT ALWAYS it gives me hard time when i start it up in the morning. Also when the car in drive the engine shacks little bit??? what could be the problem with my babe??
