 \\; \\; \\; \\; Im trying to gather information for a friend with a 04 Road King \\; .
With a P0108 code . Bike seems to lose power as if it runing out of fuel above 2500 rpm .
 \\; \\; \\; \\; \\; \\;&n bsp\\; \\; \\; Code was cleared but comes back I have read electrical manual but am wondering if the MAP sensor itself could be the cause . What else could I look for
I have changed the MAP sensor . The problem still exists.
What I have noticed was with the MAP sensor disconected . I powered up the ignition . As expected it recorded a P0108 and a P0107 . This I had expected it to do .
A strange thing I noticed while test driving ,was it seems that the throttle wont open more than 1/3 when the condition occurs . Im wondering if there is a relation to either the TP sensor because it shares power with the MAP sensor . Or could throttle opening be effected by the cruise control in some way .
On further inspection . I have found that there is a broken Throttle plate shaft . I have heard of this on rare occasions but never came across one before . The parts book shows no replacement part for that . Can anyone help me locate one for a Delphi system ?
