the truck runs pretty good overall,but when decelerating,the revs come down in steps with some pauses. for example if im in park and i accelerate to 2500 rpm and let go the gas pedal,it will stay for a second at 2500 rpm and then stop at 2000rpm for another second and so on till 750. i can also fill it while driving in "D" but more settle. idle is smooth at 750rpm and the only code i have is j1850. i guess it would be a dirty/damaged connector but where?thanks for any tips!
