[DML] Re: IDLE ISSUES(FIXED)-No Acceleraration

Typically people tweak the mixture, usually richer, to compensate for the additional air from vacuum leaks. It seems to correct the problem but it leans out under acceleration. Another major cause for people to tweak the mixture screw richer is to get the motor to run when the Lambda system is not functioning. Normally the Lambda will add *just* enough fuel to make the mixture correct. When it doesn't work the motor will run lean and stumble badly when accelerated. Fix the vacuum leaks and make sure the Lambda is working. You might also have issues with the vacuum advance. That can also cause poor acceleration and horrible fuel economy. Since you said you took the top apart it could be a lot of things. Make sure you put the little ground wire by the front, right of the motor back on and recheck ALL of the ground wires on the front of the motor too. If you can, put the mixture screw back to it's origional position. Another major cause of poor cold performance is a bad Control Pressure Regulator. Best verified with a fuel pressure gauge or substitution of a known, good unit.
