Hello everyone i am new here. i have recently aquired a 68 newport custom 2 dr with a 383. This is my first mopar and so far i couldnt be happier. Problem i am having is that ill start the car up and it idles fine. if i tap on the gas the idle jumps up and stays up. in past i have had cars where if you tap gas again it returns to normal but this doesnt. any suggestions?

 

Might need a chock pull off....

 

Choke sticking, throttle cable adjusted too tight, throttle shafts worn, vacuum leak,
