I know that sounds strange in a diesel forum, but its the best word for my problem. I was coming home the other night and when I pulled into the drive the car revved up like the pedal was to the floor. after I i turned it off, I looked under the hood to see that the mechanical linkage the accelerator actuates was stuck. i wiggled it and it snapped back to normal. It then appreared to be loose and in need of adjustment. What should I do to fix this problem?
