working on a 99 kenworth with S60. Just did lower end bearings, cylinder head, and injectors. Have double checked all part numbers and settings. Engine runs great with park brake set, as soon as you release the park brake it stumbles and runs like garbage. Set the park brake and it goes back to running perfect. Have cycled the park brake switch numerous times and pushed through all rpm ranges. No programming changes were made other than updating the cal codes. Have replaced the park brake switch and made no change. Half engine mode is disabled. No other electrical repairs were made. Any help or hints would be helpful
