Your fuel pressure is too low. Turning the screw clockwise will increase the pressure. The range is 9-13, but anything less than 13 is just giving away power. I have several TBI systems in service and none of them are run less than 13--most are 15psi. Any more than 15 without burning a prom for it and it will run too rich (make good power doing it though). Now, I am not saying this will fix your problem, but it should be addressed before remoing any more of your hair trying to solve your drivability issue. Oh, and the drips from your exhaust are condensate, not fuel. So crank up the pressure to at least 13psi and see what happens. If it doesn't fix it, give it some more and see what happens. These injection systems were notoriously lean from the factory, so some more fuel pressure will help that situation as well.
