Your problems can be described in 2 words VACUUM LEAKS This is the biggest and most common cause of engine quality complaints. There are so many potential places for vacuum to leak and you have to check and fix them ALL. Other less likely and more unusual possabilities are: Mechanical and/or vacuum advance Fuel quality and contamination Ignition parts breaking down under load (old, worn out) Mixture out-of-adjustment Lambda not functioning or not functioning correctly Listen for the frequency valve to buzz when the motor is running. If it isn't you may have found one of your problems.
