Had some engine work done on my 350 4bbl. Guy put a new return spring on the accelerator that is not right.
The car rev's ok, but when moving the gas pedal is jerky. Can't decide if the spring is too light or too heavy.

 

Is it a double spring set up? Those are are available from Dorman part number 59207

 

 

A double spring set up is a lot better and safer .Just incase a spring breaks ,

 

I took all of the slack out of the spring by stretching it making it weaker. Seems to have helped some. Gonna stretch it out a bit more . I have another one
just in case it goes too far,
