Check out the Lambda system. Make sure it is running. You may have to lean the mixture to get it to run right. Too often instead of replacing parts someone will figure they can make it run better by twiddling (I don't call it "adjusting") things. If the mixture is too rich the Lambda will hardly run at all trying to lean the mixture. If the Lambda is dead it can have these symptoms. If the Lambda is not running either the relay is bad or the O2 sensor is contaminated. Most common problems. Also make sure the little wire on the right side of the manifold toward the front of the motor is connected to the manifold (grounded) and it is still plugged in. This can also be the CPR and/or vacuum leaks. Besides looking for leaks make sure all the hoses are hooked up correctly. Check the mechanical AND vacuum advance too. Make sure all the ignition wires are snapped tightly onto the sprak plugs.
