Whenever I am slowing down, if I clutch or go to neutral, the RPMS instantly drop to about 950 (current idle speed) then bounce up to 1700-1900 and falls very, very slowly, and wont come all the way back down to 950 until I come to a complete stop.
Ok thats my issue, Ive had people tell me its the throttle cracker table (didnt think gen 4 had that table), Final air flow minimum,coatdown table etc.
Any light that can be shed on this would be appreciated.
Thanks
Mike
