Louie,

The butterfly valves in the throttle body may be sticking. Remove the 4
bolts that hold the horns (W shaped pipe at the back of the intake
manifold) in place and remove the horns. You can now see the butterfly
valves in the center of the engine. Use some carb cleaner on it and
re-assemble.

I tried lubing the linkage... still the throttle will stick at about 1100-1400 rpm's after the car has been driven. I can revv the engine and it will get enough momentum to make the throttle arm return all the way. What should I do? Is a new throttle spool spring an option? Obviously I need more tension.
