George, Your throttle switch is out of position for sure. But, don't start there. Replace your fuel filter if you haven't yet. D-jet is very easy...the problem is people start at point L, instead of A. First, Check and adjust your throttle stop/Air gap adjustments including if your throttle cable is not too tight (will cause surging). Then check your throttle position switch with a meter. After using the meter, turn your ignition switch on, and slowly turn the throttle by hand. You will hear little clicks, you must have twenty clicks or it will never run right. Sometimes you can adjust it with a meter but it won't be right unless you have twenty clicks. Then check your ignition contact points in the distributor (both sets). Don't worry about those sensors that you mentioned those are correct. Don't mess with the manifold pressure sensor until the very end. Also you will need to adjust your mixture via the adjustment knob on your computer. To the right is lean and left rich. Start all the way right, and work back until it starts to run rough. Don't run it over lean or you will cause valve damage. Lastly, the manifold pressure sensor is supposed to be non-adjustable, however I'm sure yours has been fooled with as most have been through the years. You will see a small allen or a screw beneath the cap in the back. Very small adjustments in or out will improve performance. This adjustment could take awhile.
