Nice car!

First evil servo! Evil servo!

Second everything on this car is controlled by vacuum...all your linkages are in place but your transmission is also vacuum controlled. You probably need to rebuild the vacuum pump...find the leaks etc....also another cause, is if the engine isn't running up to power the transmission won't either...

You have the egr system on this car too....you will have to remove that and clean the soot out of the intake manifold.

Just remove the tank and clean it, very simple....and you won't have issues regarding gunk or algae afterwards...

Also you probably need a new primer pump, old ones leak and suck air...

Probably need new injectors...

Shaking means you also need new motor mounts and trans mount.

Finally the non turbo engines are big time slugs! Going up a hill here at altitude....I am lucky to keep 55mph.....give me an incline and I can get up to 90!

Also look into redoing the shifter bushings....so your car won't roll away from you with out you in it....
