i change the alda on my 1985 300 turbo diesel California .the car now has no power , takes a lot to get speed ,when i am in higher gear does not downshift and if i put the pedal all the way down is no diference very weak. it does has a lot of power when it starts from 1 gear ,if i keep the throtle down.can it be vacuum issue. i am also thinking to bypass the blue saucer.where can i find a diagram with the bypass .thanks

where did you get the alda you changed to? the alda regulates fuel based on boost, so you might have a boost line plugged, or broken. the alda needs to be calibrated with washers of varying thickness to function correctly.

i bought the alda as used part.i did not put any washers.the part where is adjusting at the top looks like is stock ,it is sealed. before putting the alda in the car was running good .does the vcv valve has anything to do with this?
