Ignition pickup sensor - 91 Flhtc
 

I think my ignition sensor is broken. The problem is: When I'am crusing at, approximately 80 kmh and rpm at 26-2700 for a distanse of 70-80 km it seems ok, but when I reach 3000 rpm the engine starts to cut. If I then cut the ignition in speed (70-80 km) and start up again, the symtoms dissapears.
The insulation around the sensor is sticky and seems to melted, I know this might be a sign to get a new one? Are you guys agree?
And another question, can I use a sensor from a newer Evo? Part # 32488-95
Thank's
